questions about how many grams of a product completely react in the reactions

1. For the reaction Ca(s)+Cl2(g)→CaCl2(s) calculate how many grams of the product form when 21.4 g of Ca completely reacts. Assume that there is more than enough of the other reactant.

2. For the reaction 2K(s)+Br2(l)→2KBr(s) calculate how many grams of the product form when 21.4 g of Br2 completely reacts. Assume that there is more than enough of the other reactant.

3. For the reaction 4Cr(s)+3O2(g)→2Cr2O3(s) calculate how many grams of the product form when 21.4 g of O2 completely reacts. Assume that there is more than enough of the other reactant.

4. For the reaction 2Sr(s)+O2(g)→2SrO(s) calculate how many grams of the product form when 21.4 of Sr completely reacts. Assume that there is more than enough of the other reactant.
