Question

Assuming you do know the value of R (0.08206 L atm/mol-K), what volume of H₂ gas would you expect to collect?

a) 1.0 L
b) 2.0 L
c) 3.0 L
d) 4.0 L

Answer 1

The volume of H₂ gas to be collected can be calculated using the ideal gas equation. By substituting the given values into the equation and solving for volume, we find that the expected volume is 22.42 L.

Step-by-step explanation:

If we assume the value of R to be 0.08206 L atm/mol-K, we can use the ideal gas equation to calculate the volume of H₂ gas. The equation is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

Since the pressure, temperature, and gas constant are known, we can rearrange the equation to solve for volume. V = nRT/P.

Substituting the given values, we have: V = (1 mol)(0.08206 L atm/mol-K)(273 K)/(1 atm) = 22.42 L

Therefore, the correct answer is a) 1.0 L.
