Question

How many moles of carbon dioxide at STP will fit in a 50 liter container?

Answer 1

n = 2.23 moles

Step-by-step explanation:

Given the following data;

Standard temperature = 273 K

Standard pressure = 101.325 kPa

Volume = 50 liter

R = 8.314 J/mol·K

To find the number of moles, we would use the ideal gas law formula;

PV = nRT

Where;

• P is the pressure.
• V is the volume.
• n is the number of moles of substance.
• R is the ideal gas constant.
• T is the temperature.

Making n the subject of formula, we have;

`n = \frac {PV}{RT}`

Substituting into the formula, we have;

`n = \frac {101.325*50}{8.314*273}`

`n = \frac {5066.25}{2269.722}`

n = 2.23 moles

Therefore, 2.23 moles of carbon dioxide at STP will fit in a 50 liter container.
