Calculate the mass of chlorine gas which occupies a volume of 1.12dm3 at s.t.p
[Cl = 35.5, molar volume of gas at s.t.p = 22.4 dm3
[Cl = 35.5, molar volume of gas at s.t.p = 22.4 dm3
-
A.
15.50 g -
B.
7.10 g -
C.
3.55 g -
D.
1.80 g
Correct Answer: Option C
Explanation
2 * 35.5g of chlorine has a volume of 22.4 dm3 at s.t.p
∴ xg of chlorine will have a volume of 1.12 dm3x = (1.12 * 35.5 * 2)/22.4 = 3.55g
