Calcium carbonate, CaCO3 (also called calcite), is the principal mineral found in limestone, marble, chalk, pearls, and the shells of marine animals such as clams. A certain sample of calcium carbonate contain 4.86 moles. What is the mass in grams of this sample?

486 grams

Explanation:

No of moles = mass in gram / molar mass

Mass in gram = No of moles × molar mass

Molar mass of CaCO3 = 40+12+(16*3)

= 40+12+48 = 100 amu

Mass in gram = 4.86 × 100

Mass in gram 486 grams

i think so it’s will be b yes i believe its

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
