Find the mass of CO₂ produced with 365g of HCl. The equation is below. CaCO₃ + 2HCl —> CaCl₂ + H₂O + CO₂
The mass of CO₂ produced is 220g
Find the mass of CaSO₄ when the mass of Ca is 2g. Equation is below. Ca + H₂SO₄ —> CaSO₄ + H₂
The mass of CaSO₄ is 6.8g
What is the GFM of C₆H₁₄
6 x 12 = 72 14 x 1 = 14 Total = 86g
Calculate the GFM of Fe₂(SO₄)₃
2 x 56 = 112 3 x 32 = 96 12 x 16 = 192 Total = 400g
What is the % of O in HCO₃?
1 x 1 = 1 1 x 12 = 12 3 x 16 = 48 Total = 61g So the % of O in HCO₃ is: 48/61 x 100 = 78.7%
What is the % of P in CaH₄P₂O₈?
1 x 40 = 40 4 x 1 = 4 2 x 31 = 62 8 x 16 = 128 Total = 234g So the % of P in CaH₄P₂O₈ is: 62/234 x 100 = 26.5%
