Question

How many moles of ba(oh)2 are in 2400 grams of ba(oh)2?

Answer 1

Answer: 14.01 moles

To solve this question, you need to determine the molecular mass of the Ba(OH)2. The molecular mass would be: 137.3 + 2(16+1)= 171.3g/mol.

If the total weight of Ba(OH)2 is 2400g and its molecular mass is 171.3g/mol, the number of moles would be: 2400g/ (171.3g/mol)=14.01 moles
