3.00 moles of gas are in a container with a volume of 60.0 liters and at a temperature of 400. K What is the pressure inside the container?

Question

Did I do this right?

P#xx# 60 = 3 #xx# 0.0821 #xx# 400
P #xx# 60 = 98.52
P = 0.61

If i did it wrong, can you tell me what i need to improve on? I also have another question. When i get to the last step where i need to divide, which number do i divide with? The number with the unknown variable?

The pressure of the gas is 1.64 atmospheres.

To solve this problem, we need to use the ideal gas law:

#PV=nRT#

#P# is pressure in atmospheres, #V# is volume in liters, #n# is moles, #R# is the universal gas constant, and #T# is the temperature in Kelvins.

Plug the known values into the equation and solve for the pressure.

#(P)(60.0)=(3.00)(0.08206)(400)#

#P=((3.00)(0.08206)(400))/(60.0)=1.64# atm
