1 mole of mass of ca (OH) 2 = 40*1 + (16 + 1) 2 = 40 + 34 = 74g.
So, mass of 24 moles = 24*74 = 1776g.
To find the mass of 7.21 x 10^24 atoms of phosphorus (P), you need to know the atomic mass of phosphorus. The atomic mass of phosphorus is approximately 31 grams per mole. By calculating the molar mass and dividing it by Avogadro's number, you can determine the mass of 7.21 x 10^24 atoms of phosphorus.
Approximately 2 / (6.022 x 1023) = 3.32 x 10-24 grams
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ratio of isotopes equal to that in nature - has a mass of 12.0107 grams.
The molar mass of a substance in dalton units can be converted to grams per mole (g/mol) by multiplying the dalton value by 1.66054 x 10-24. This conversion factor allows you to express the molar mass in grams per mole.

The eastern mole weighs about 75 grams individually. A mole of these moles would weigh 4.52 E22 kilograms. The mass of the Earth is estimated at 5.97219 E 24 kilograms. This reduces to 4520/597219 or .007568, which is .7568 percent.
The molar mass of ferric ammonium citrate is approximately 270.00 g/mol.

One mole of gold has a greater mass than one mole of silver because gold has a higher atomic mass compared to silver. The atomic mass of gold is around 197 grams per mole, whereas the atomic mass of silver is around 108 grams per mole.
39.95 because that is the molar mass of Argon
