How many cups are in $1$ gallon?

16 cups

How many teaspoons are in $1$ cup?

48 teaspoons

Use mixed units of measurement in the u.s. system

Performing arithmetic operations on measurements with mixed units of measures requires care. Be sure to add or subtract like units.

Charlie bought three steaks for a barbecue. Their weights were $14$ ounces, $1$ pound $2$ ounces, and $1$ pound $6$ ounces. How many total pounds of steak did he buy?

Solution

We will add the weights of the steaks to find the total weight of the steaks.

 Add the ounces. Then add the pounds. Convert 22 ounces to pounds and ounces. Add the pounds. 2 pounds + 1 pound, 6 ounces 3 pounds, 6 ounces Charlie bought 3 pounds 6 ounces of steak.

Laura gave birth to triplets weighing $3$ pounds $12$ ounces, $3$ pounds $3$ ounces, and $2$ pounds $9$ ounces. What was the total birth weight of the three babies?

9 lbs. 8 oz

Seymour cut two pieces of crown molding for his family room that were $8$ feet $7$ inches and $12$ feet $11$ inches. What was the total length of the molding?

21 ft. 6 in.

Anthony bought four planks of wood that were each $6$ feet $4$ inches long. If the four planks are placed end-to-end, what is the total length of the wood?

Solution

We will multiply the length of one plank by $4$ to find the total length.

 Multiply the inches and then the feet. Convert 16 inches to feet. 24 feet + 1 foot 4 inches Add the feet. 25 feet 4 inches Anthony bought 25 feet 4 inches of wood.

Henri wants to triple his spaghetti sauce recipe, which calls for $1$ pound $8$ ounces of ground turkey. How many pounds of ground turkey will he need?

4 lbs. 8 oz.

Joellen wants to double a solution of $5$ gallons $3$ quarts. How many gallons of solution will she have in all?

11 gal. 2 qts.

Make unit conversions in the metric system

In the metric system, units are related by powers of $10.$ The root words of their names reflect this relation. For example, the basic unit for measuring length is a meter. One kilometer is $1000$ meters; the prefix kilo- means thousand. One centimeter is $\frac{1}{100}$ of a meter, because the prefix centi- means one one-hundredth (just like one cent is $\frac{1}{100}$ of one dollar).

The equivalencies of measurements in the metric system are shown in [link] . The common abbreviations for each measurement are given in parentheses.

Metric Measurements
Length Mass Volume/Capacity
$1$ kilometer (km) = $1000$ m
$1$ hectometer (hm) = $100$ m
$1$ dekameter (dam) = $10$ m
$1$ meter (m) = $1$ m
$1$ decimeter (dm) = $0.1$ m
$1$ centimeter (cm) = $0.01$ m
$1$ millimeter (mm) = $0.001$ m
$1$ kilogram (kg) = $1000$ g
$1$ hectogram (hg) = $100$ g
$1$ dekagram (dag) = $10$ g
$1$ gram (g) = $1$ g
$1$ decigram (dg) = $0.1$ g
$1$ centigram (cg) = $0.01$ g
$1$ milligram (mg) = $0.001$ g
$1$ kiloliter (kL) = $1000$ L
$1$ hectoliter (hL) = $100$ L
$1$ dekaliter (daL) = $10$ L
$1$ liter (L) = $1$ L
$1$ deciliter (dL) = $0.1$ L
$1$ centiliter (cL) = $0.01$ L
$1$ milliliter (mL) = $0.001$ L
$1$ meter = $100$ centimeters
$1$ meter = $1000$ millimeters
$1$ gram = $100$ centigrams
$1$ gram = $1000$ milligrams
$1$ liter = $100$ centiliters
$1$ liter = $1000$ milliliters

To make conversions in the metric system, we will use the same technique we did in the U.S. system. Using the identity property of multiplication, we will multiply by a conversion factor of one to get to the correct units.

where we get a research paper on Nano chemistry....?
nanopartical of organic/inorganic / physical chemistry , pdf / thesis / review
Ali
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level

ya I also want to know the raman spectra
Bhagvanji
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think

is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong

why surface tension is zero at critical temperature
Shanjida
I think if critical temperature denote high temperature then a liquid stats boils that time the water stats to evaporate so some moles of h2o to up and due to high temp the bonding break they have low density so it can be a reason
