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 \(CaCO_{3}\)<br />### The molar mass of \(CaCO_{3}\) 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 \(CaCO_{3}\), the total molar mass is:<br />\[ \text{Molar mass of } CaCO_{3} = 40.08 + 12.01 + (3 \times 16.00) = 100.09 \, \text{g/mol} \]<br /><br />## Step 2: Use the molar mass to go from moles to grams<br />### To find the number of grams in 3.25 moles of \(CaCO_{3}\), multiply the number of moles by the molar mass:<br />\[ \text{Mass} = \text{Number of moles} \times \text{Molar mass} \]<br />\[ \text{Mass} = 3.25 \, \text{moles} \times 100.09 \, \text{g/mol} = 325.29 \, \text{grams} \]
