Values of R, the ideal gas constant, and the ideal gas equation are given below. Use these to solve the problems. PV = nRT
A 10.0-L rigid container holds 3.00 mol H2 gas at a pressure of 4.50 atm. What is the temperature of the gas? (Round to the nearest whole number)
K

183 K

General Formulas and Concepts:

Chemistry - Gas Laws

Combined Gas Law: PV = nRT

P is pressureV is volume (in Liters)n is amount of molesR is gas constant - T is temperature (in Kelvins)

Explanation:

Step 1: Define

10.0 L

3.00 mol H₂

4.50 atm

Step 2: Find Temperature

Substitute [CGL]:                    Isolate temperature x:                                                                                    Rewrite:                                                                                                           Evaluate:                                                                                                        

Step 3: Check

Round to the nearest whole number.

182.704 K ≈ 183 K
