Gram is a unit of mass. Just look at the number that comes before 'gram'. That's the mass, in grams.
Ammonium sulfate contains 21% nitrogen by mass. To find the mass of nitrogen in 148 grams of ammonium sulfate, you would first calculate 21% of 148 grams, which equals 31.08 grams of nitrogen.
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58.5 grams20.0 grams NaCl / (58.5 grams) =.342 moles NaCl
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.
mole = mass/molar mass mass=2.3 grams molar mass=30.97 2.3/30.97=0.0742 moles
Grams are mass. There's no calculation involved.
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.
Subtract the mass of the beaker from the total weight.
To find the mass of 1.54 moles of H2O, you can use the molar mass of water. The molar mass of H2O is 18.015 grams/mol. Therefore, the mass of 1.54 moles of H2O would be 1.54 moles * 18.015 grams/mol = approximately 27.75 grams.
the mass is the 50 grams you probably need the volume volume = mass / density get the density from tables
Simple: the atomic weight expressed in grams. Example for dysprosium - 162,500 grams.
To calculate the mass of methanol (CH3OH), we first need to find the molar mass of CH3OH. The molar mass of CH3OH is approximately 32 grams per mole. By multiplying the molar mass by the given amount of 9.85x10^24 molecules, we can find the mass in grams, which is about 3.15x10^26 grams.
To calculate the mass of 2x10^12 atoms of potassium, you first need to find the molar mass of potassium (39.10 g/mol). Then, divide the number of atoms by Avogadro's number to get the moles of potassium. Finally, multiply the moles by the molar mass to find the mass in grams, which in this case would be 0.01566 grams.
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.
The mass of 60 grams is 60 grams, the mass of 0 grams is 0 grams, and the mass of 2.2 grams is 2.2 grams.
To find density, divide the mass by the volume. In this case, the density would be 55.6 grams divided by 3.2, which equals 17.375 grams per cubic centimeter.
You use grams to find the mass of an object.
People wanted to find out the exact amount of mass an object has. So people simplified kg into grams.
