Question

At STP, how many moles of carbon dioxide will occupy 35.2 L of space?

Answer 1

Moles of carbon dioxide are 1.57

Step-by-step explanation:

Using ideal gas law, you can find moles of a gas with its pressure, temperature and volume, thus:

PV = nRT

PV/RT = n

Where P is pressure, V is volume (35.2L); R is gas constant (0.082atmL/molK); T is absolute temperature and n are moles

At STP, temperature is 273.15K and pressure is 1atm

Replacing:

1atm×35.2L / 0.082atmL/molK×273.15K = n

1.57 = n

Moles of carbon dioxide are 1.57
