The total pressure of the mixture of gases is
equal to the sum of the pressure of each gas as if it is alone in the
container. The partial pressure of a component of the mixture is said to be
equal to the product of the total pressure and the mole fraction of the
component in the mixture.<span>
Partial pressure of hydrogen gas = 1.24 atm x
.25 = 0.31 atm
<span>Partial pressure of the remaining = 1.24 atm x
(1-.25) = 0.93 atm </span></span>
Answer:
0.206 mol H₂O₂
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
7.00 moles H₂O₂
<u>Step 2: Identify Conversions</u>
Molar Mass of H - 1.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H₂O₂ - 2(1.01) + 2(16.00) = 34.02 g/mol
<u>Step 3: Convert</u>
<u />
= 0.205761 mol H₂O₂
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
0.205761 mol H₂O₂ ≈ 0.206 mol H₂O₂
