Answer to Question #301614 in General Chemistry for Jason

Question

1. What volume of carbon dioxide is formed, at r.t.p., by burning 100 g of carbon? The equation is:

C(s) + O 2 (g)  CO 2 (g).

2. What is the volume of 6.50 mol of nitrogen gas at r.t.p.?

3. What volume would 200 g of SF 6 occupy at room temperature and pressure?

4. Methane reacts with steam to produce carbon monoxide and hydrogen, according the following

equation: CH 4 (g) + H 2 O(g)  CO(g) + 3H 2 (g)

What volume of H 2 , at room temperature and pressure, would 20 g of methane produce?

5. Burning propane, C 3 H 8 , forms carbon dioxide and water according to the equation: C 3 H 8 + 5O 2

3CO 2 + 4H 2 O. If 50 dm 3 of CO 2 , at r.t.p., was formed, how many grams of propane was burned?

Answer 1

mass of C3H8 = moles x MM = 0.694mol x 44.1g/mol

= 30.625g
