Question

Calculate the amount, in moles, of each of the following.You may round atomic masses to one decimal place.5.39 g CdS

Answer 1

1) Convert grams of CdS into moles of CdS.

MM (CdS): 144.5 g/mol.

`molCdS_{}=5.39gCdS_{}\cdot\frac{1molCdS_{}}{144.5gCdS_{}}=0.03730molCdS`

5.39 g of CdS is equal to 0.03730 mol CdS.
