1 mole = 24dm^3, which is 24,000cm^3

The problem states 50 cm^3, so we need to use the 24,000 cm^3 number.

Volume of gas at room temperature = number of moles x 24,000 cm^3

50 cm^3 = number of moles x 24,000 cm^3

Number of moles = 50 cm^3 / 24,000 cm^3

Number of moles = 0.00208333 (round answer as needed)

0.22397 moles of gas were collected.

Given that 50cm³ of a gas were collected during a reaction, which was carried out at room temperature and pressure, to determine how many moles of the gas were collected, the following calculation must be performed:

To determine the number of moles of a gas, you must multiply the volume and pressure of the gas, and divide this result by the temperature multiplied by the value of molar gas constant, which is 8.3144598.

  • 50 x 1 / 26.85 x 8.3144598 = X
  • 50 / 223.24 = X
  • 0.22397 = X

Therefore, 0.22397 moles of gas were collected.
