Problem 90P

PROBLEM 90P

Consider the chemical reaction:

2H2O(l) → 2H2(g) + O2(g)

How many moles of H2O are required to form 1.3 L of O2 at 325 K and 0.988 atm?

Step-by-Step Solution:

Step 1 of 3

Solution 90P

Balanced equation:

2H2O(l) → 2H2(g) + O2(g)

2 mol H2O produce 1 mol O2

Use Gas Law Equation to calculate mol of O2

PV = nRT

0.992*1.3 = n * 0.082057*315

n = 1.2896/ 25.848

n = 0.04989 = 0.05 mol O2 produced.

From equation, this will require: 0.05*2 = 0.1mol H2O

If you require the mass of water:

Molar mass H2O = 18g/mol

0.1mol H2O = 18*0.1 = 1.8g H2O required.
