Question

What is the molar mass of copper 1 carbonate when rounding to the nearest whole number of copper 56 and carbon 12 and oxygen 16

Answer 1

172 g/mol

Step-by-step explanation

The chemical formula of copper I carbonate is Cu₂CO₃

Using the given molar masses of:

Cu = 56 g/mol

C = 12 g/mol

O = 16 g/mol

The molar mass of Cu₂CO₃ = (2 x 56 g/mol) + 12 g/mol + (3 x 16 g/mol)

Cu₂CO₃ = 112 g/mol + 12 g/mol + 48 g/mol

Cu₂CO₃ = 172 g/mol
