If the pressure exerted by a gas at 25 degrees C in a volume of 0.044 L is 3.81 atm, how many moles of gas are present?

About n=6.765 * 10^-5 moles

Step-by-step explanation:

Using PV=nRT, you can start by plugging these numbers in.

25 degrees celsius is 298 degrees Kelvin.

3.81 * 0.044=n *R * 298

Dividing both sides by 298 and the universal gas constant, you get about:

n=6.765 * 10^-5 moles.

Hope this helps!
