If you place a 500 gram weight on a 1 inch x 1 inch paint sample is it the same weight per square inch if you place 5 1 inch samples under the same 500 grams?
The support provided by 5 samples would be 5 times greater than that of 1 sample, but the weight expressed by the 500 gram weight remains constant.
Test samples at 0.17 gram 0.204 gram and 2.3 grams What is the total weight of the three samples?
2.674 g

0.02
What is 600 grams divided by 4?
150
What is the density of a sample that has a mass of 36 grams and a volume of 12 milliliters?
Density = mass/volume, so:36 grams/ 12 milliliters3 grams/ milliliter
A chemist weighed three separate test samples at 0.17 gram 0.204 gram and 2.3 grams What is the total weight of the three samples?
2.674 grams

a metal sample weigs 56.8 gramsHow many ounces does this sample weigh?
Which has the greatest number of atoms- 45 grams of Mg 45 grams of F 45 grams of P or 45 grams of Na?
In order to figure out how many atoms are in each sample, you would take 45, multiply it by 6.02 × 1023, and divided by the atomic mass. Since two of the numbers (45 and 6.02 × 1023) will be constants in all of the samples, the number of atoms will differ in each sample due to the atomic mass. 45 × (6.02 × 1023) / atomic mass in grams = number of atoms You could punch out all the numbers to see which sample has the greatest number of atoms, but it is easier to find the atomic mass for all of them and see which one is smaller. A larger atomic mass will mean the equation will be divided by a larger number, meaning the number of atoms will be smaller. So the smallest atomic mass would yield more atoms.Atomic masses:Mg- 24.3 grams***F- 38.0 gramsP- 31.0 gramsNa- 23.0 grams***Note that fluorine is a diatomic moleculeThe sample of 45 g of sodium (Na) would contain the greatest number of atoms
How many grams does a 0.0233 kg sample contain?
23.3 grams
A sample of seawater has a mass of 158 grams and a volume of 156ml what is its density?
Divide 158 by 156. The answer is the density in grams per ml. In this case, very close to 1 g/ml Density = MASS divided by VOLUME

A sample of 0.53 grams of an ore contains 5.4 percent silver How many milligrams of pure silver are in the sample?
Approx 28.6 grams.
The mass of Denise's rock sample is 684 grams. The mass of Pauline's rock sample is 29,510 centigrams. How much greater is the mass of Denise's sample than Pauline's sample?
"centi" is 100. 1 centigram is 100 grams, so Denise's sample is 68,400 centigrams. 68400 - 29510 = 38890 centigrams or 388.90 grams.
What is 5 grams divided by 250 milligrams?
0.02
A 10 ml sample of a substance has a mass of 20 grams what would be the mass of a 200 ml sample of the same substace?
The second sample is 200/10 = 20 times as large. So its mass will be 20 times as great ie 20*20 grams = 400 grams.
