A pure gold coin contains 0.145 mol of gold. What is its mass?
Step 1 of 3
Given : Pure gold contains 0.145 mol of gold
Mass of gold = ?
Molar mass of gold (Au) = 196.96 g/mol.
This means, 1 mole of gold = 196.96 g of gold.
Hence, becomes the conversion factor.
Now to find the mass of Au we multiply the given mol of Au with the conversion factor.
= 28.552 g
Hence, mass of gold is 28.552 g
