Question

What is the mass of 0.00456 moles of alum?

Answer 1

Step-by-step explanation:

N = 14.007 g/mol

H = 1.008 g/mol

S = 32.065 g/mol

O = 16 g/mol

2(14.007) + 8(1.008) + 32.065 + 4(16) = 132.143 g/mol

Now you know how much an entire mol weight you multiply it by how much you actually have

0.00456 * 132.143 = 0.603 g
