What is the RAM of H₂?
2
What do you have to do to the RAM of diatomic elements
Double it
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%
