Gram is a unit of mass. Just look at the number that comes before 'gram'. That's the mass, in grams.
32 grams, you can find the mass of one mole of any element by looking at its atomic mass eg chlorine has Atomic mass of 35.5 so the mass of one mole of chlorine is 35.5 grams.
molar mass divided by atomic mass times 6.02 x 1023 =)
Grams are mass. There's no calculation involved.
You are given moles and need to find grams, the atomic mass of any element is in g/mol so just go to the periodic tables and Cu which is copper has a mass of 63.546 grams/ mole. Then you know if you multiply Mole * g / mol the moles will cancel out and you will be left with grams so .0420 mol Cu * 63.546 g / mole Cu = 2.669 grams
52.1grams. moles = mass (in grams)/RMM (relative molecular mass) 1.3 moles = mass (in grams)/ 40.078 mass = 40.078 x 1.3 = 52.1grams
To find the mass, we divide by Avogadro's number to find the amount of moles. We then multiply the moles by the molar mass of the compound which is 60.08 grams. Doing all of this, we get a mass in grams of 5.59 grams.

the mass is the 50 grams you probably need the volume volume = mass / density get the density from tables
To find the answer, we multiply the 7 grams of NaCl by the ratio of the molar mass of chlorine over the molar mass of sodium chloride. By doing this, we find that there are about 4.25 grams of chlorine in 7 grams of NaCl.
Unfortunately, an animals kilometers are not a measure of mass. If you knew the volume of the animal and the density you could find the mass in grams.
People wanted to find out the exact amount of mass an object has. So people simplified kg into grams.
Grams. Matter is measured by mass and mass's main unit is grams.
You use grams to find the mass of an object.

I assume the correct units for the density is 3.14 grams per milliliter. So if you have 93.5 grams of a substance with a density of 3.14 grams per milliliter, then you divide the mass by the density to find volume. 93.5 grams/3.14 grams/ml = 29.77 ml
To convert grams to moles, you need to know the molar mass of the substance. Divide the given mass in grams by the molar mass to find the number of moles. This calculation is done using the formula: moles = grams / molar mass.
