Select all answers that apply when describing the correct steps needed to solve the following problem. How many grams are in 3.25 moles of calcium carbonate (CaCO_(3)) Calculate the molar mass of CaCO_(3) D Use 22.4 as the conversion factor to go from grams to moles D Calculate the number of molecules in 1 liter Use Avogadro's number to go from grams to liters Use the molar mass to go from moles to grams

## Step 1: Calculate the molar mass of ### The molar mass of is calculated by adding the atomic masses of calcium (Ca), carbon (C), and oxygen (O). The atomic masses are approximately 40.08 g/mol for Ca, 12.01 g/mol for C, and 16.00 g/mol for O. Since there are three oxygen atoms in , the total molar mass is: ## Step 2: Use the molar mass to go from moles to grams### To find the number of grams in 3.25 moles of , multiply the number of moles by the molar mass:
