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

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
