gram-gram stochiometry practice
3Ca(OH)2+2H3PO4→Ca3(PO4)2+3H2O
Use dimensional analysis to calculate how many grams of H2O will be produced if 111.5 grams of Ca(OH)2 are reacted.
Hint: You will need to find the molar mass of Ca(OH)2 and the molar mass of H2O.
2 C4H10 + 13 O2 → 8 CO2 + 10 H2O
Using dimensional analysis calculate how many grams of CO2 are produced when 100 grams of butane, C4H10, gas are reacted.
Hint: You will need to calculate the molar mass of CO2 and C4H10
4Fe(s)+3O2(g)→2Fe2O3(s)
Use dimensional analysis to calculate how many grams of iron (iii) oxide, Fe2O3 are produced if 55 grams of iron are reacted.
Hint: You will need to calculate the molar mass of Fe2O3 and Fe
P4 + 6Cl2→ 4PCl3
Using dimensional analysis calculate how many grams of phosphorus are reacted if 250g of phosphorus trichloride, PCl3 , are produced
