How many grams are there in 2.5 moles of Ca(OH)2?

185 grams

Explanation: First find out how many grams are in one mol: The molar mass es are taken from the periodic table, Ca is 40, O is 16, H is 1. There are 2 O and 2 H for (OH)2: 40+32+2= 74g/mol x 2.5 mol = 185 the moles cancel and you are left with grams
