Q:

50cm³ of a gas were collected during a reaction. The reaction was carried out at room temperature and pressure. How many moles of the gas were collected?

Accepted Solution

A:
1 mole = 24dm^3, which is 24,000cm^3The 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^350 cm^3 = number of moles x 24,000 cm^3Number of moles = 50 cm^3 / 24,000 cm^3Number of moles = 0.00208333 (round answer as needed)
