Answer: 138g/mol

Explanation:

K2CO3 is the chemical formula for potassium trioxocarbonate

For molar mass of K2CO3, use the molar masses:

Potassium, K = 39g;

Carbon, C = 12g;

Oxygen, O = 16g

K2CO3 = [(39g x 2) + 12g + (16g x 3)]

= 78g + 12g + 48g

= 138g/mol

Thus, the molar mass of K2CO3 is 138g/mol
