Consider the chemical reaction: C(s)+H2O(g)→CO(g)+H2(g) How many liters of hydrogen gas are formed from the complete reaction of 1.20 mol of C? Assume that the hydrogen gas is collected at a pressure of 1.0 atm and temperature of 311 K .
express your answer in 2 significant figures
Homework Answers
From given chemical equation,
Mol of H2 formed = mol of C reacted
= 1.20 mol
Given:
P = 1.0 atm
n = 0.20 mol
T = 311.0 K
use:
P * V = n*R*T
1 atm * V = 0.2 mol* 0.08206 atm.L/mol.K * 311 K
V = 5.10 L
Answer: 5.1 L
