Question

A 0.75mol calcium carbonate (CaCO3) pellet has what mass?

Answer 1

Answer:

75 g  

Step-by-step explanation:

Step 1. Calculate the molar mass of CaCO₃

Ca                    =   40.08

  C                    =   12.01

3O = 3 × 16.00 =  48.00

               Total = 100.09 g/mol

Step 2. Calculate the mass of the pellet

Mass of CaCO₃ = 0.75 mol × (100.09 g/1 mol)

Mass of CaCO₃ = 75 g
