🤓 Based on our data, we think this question is relevant for Professor N/A's class at Ryerson University.
We are asked to find the mass percent of CaCO3 in the mixture.
Assume 100 of the mixture.
Mass CO3 = 61.1 g
Molar mass CaCO3 = 100 g/mol
Molar mass (NH4)CO3 = 96 g/mol
Calculate mass CaCO3 in the mixture:
A mixture of CaCO3 and (NH4 )2 CO3 is 61.1 % CO3 by mass.
Find the mass percent of CaCO3 in the mixture.
