Question

calculate the formula mass of calcium carbonate and sodium carbonate.​

Answer 1

Answer:

Na2CO3 106 g/mol

CaCO3 100g/mol

Explanation:

2(Na)+1(C)+3(16)

2(23)+12+3(16)

106g/mol

And in the same way for CaCO3

P. S. Whereas relative atomic mass for Na is 23 amu, C is 12amu, O is 16 amu

Answer 2

Answer:

Explanation:CaCo3 =106

Na2Co3=100
