Which of the following contains the greatest number of moles of oxygen atoms?
Which of these has the greatest mass?
When 10.00 g of water partially evaporates,
water molecules are removed as vapor. Calculate the mass of water remaining.
Calcium carbonate has the formula
What is the mass of one mole of calcium carbonate to the nearest gram?
What is the mass of one formula unit of calcium carbonate to 3 significant figures?
Calculate to 3 significant figures the number of moles present in 500 g of pure calcium carbonate.
Which of the following represents the greatest mass?
