Quick Answer: How many moles are in CuSO4?

How do you calculate moles of CuSO4?

Number of moles in 24.9 g of CuSO4. 5H2O: number of moles = mass / molar mass = 24.9 / 249.72 = 0.100 mol. Note that the question gave the mass as 24.9 g – three significant figures.

How is moles calculated?

How is a mole calculated? If you want to know how many moles of a material you have, divide the mass of the material by its molar mass. … This mass is given by the atomic weight of the chemical unit that makes up that substance in atomic mass units (amu).

How many atoms are in CuSO4?

21 atoms are present in compound cuso4.

What is the mass of 0.75 moles of CuSO4?

0.75 moles* 160/mole= 120g.

What is the percent of sulfur in CuSO4?

Commercial copper sulfate is usually about 98% pure copper sulfate, and may contain traces of water. Anhydrous copper sulfate is 39.81 percent copper and 60.19 percent sulfate by mass, and in its blue, hydrous form, it is 25.47% copper, 38.47% sulfate (12.82% sulfur) and 36.06% water by mass.

Why is a mole 6.022 x10 23?

The mole (abbreviated mol) is the SI measure of quantity of a “chemical entity,” such as atoms, electrons, or protons. It is defined as the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12. So, 1 mol contains 6.022×1023elementary entities of the substance.
