Question

If the pressure exerted by a gas at 27.0°C in a vessel of volume 0.050 L is 4.00 atm, how many moles of the gas are present?

Answer 1

use the ideal gas law: \[P*V = n*R*T\] and solve for \(n\). Just be sure to convert the temperature into Kelvin, not Celsius

Answer 2

PV = nRT

Just plug in and solve for n = moles.

Must convert T into kelvin

Use 0.082 for R
