Formula mass of CaCO3 is
40 + 12 + 3-100amu....
100g CaCO3 = 1 mole..
50g of CaCO3 = 1÷ 100x 5 = 0.5mole...
<h3>Hence ,answer is 0.5mole...</h3>
Hope it helps you..
Thanks...
Answer:The Law of Conservation of Mass simply states that the total amount of mass should not change in a chemical reaction that is isolated (no other objects can enter the reaction). The total mass of the reactants must be equal to the total mass of the products. Thus, the correct estimate of the amount of oxygen used in the interaction is the difference between 133 g and 29 g.
