## How many moles are in copper II sulfate?

So copper (II) sulfate pentahydrate has a molar mass of: (63.546 x 1) + (32.066 x 1) + (15.9994 x 4) + (1.0079 x 10) + (15.9994 x 5) = 249.6856 g/mol.

## How many moles of copper II sulfate are in a 0.125 g sample of CuSO4?

How many moles of copper (II) sulfate (CuSO4) are in a 0.125g sample of CuSO4? Your answer should have three significant figures. Which scientist’s experiment determined the mass of an electron?

## What is the formula for copper II sulfate hydrate?

Copper(II) sulfate, also known as copper sulphate, are the inorganic compounds with the chemical formula CuSO4(H2O)x, where x can range from 0 to 5.

## How much copper can 100g make?

Atomic mass of Oxygen (O) is 16\$mu \$ and when expressed in terms of grams is 16 g. As, 159.5 g of Copper Sulphate (\$CuS{O_4}\$) contains 63.5 g of Copper (\$Cu\$). Hence, 39.81 g of Copper (\$Cu\$) can be obtained from 100 g of Copper Sulphate (\$CuS{O_4}\$).
