Question

Consider a container with 9.94g of N₂ gas and an unknown mass of CO₂ gas. If we know that the partial pressure of the CO₂ is twice that of N₂, determine the mass of CO₂ has in the container.

Answer 1

To determine the mass of CO₂ in the container, we can use the concept of partial pressures and the ideal gas law. By setting up an equation with the partial pressures of CO₂ and N₂, we can find the number of moles of each gas and calculate the mass of CO₂ in the container.

Step-by-step explanation:

To determine the mass of CO₂ in the container, we need to use the concept of partial pressures. Given that the partial pressure of CO₂ is twice that of N₂, we can set up an equation using the ideal gas law:

PV = nRT

Since the volume, temperature, and gas constant are constant, we can rewrite the equation as:

P1 * n1 = P2 * n2

Since the partial pressure of CO₂ is twice that of N₂, we have:

P_CO2 * n_CO2 = 2 * P_N2 * n_N2

From the given information, we know the mass of N₂ is 9.94g and we need to find the mass of CO₂. To find the number of moles of CO₂ and N₂, we can use the molar mass formula:

moles = mass / molar mass

By knowing the number of moles, we can then calculate the mass of CO₂ in the container.
