10L of a gas are stored at 20 °C and 12 atm pressure. How many moles of gas are there? ( convert temp to Kelvin )

Answer:

5.0mol

Explanation:

Use the ideal gas law, PV = nRT

P = 12atm, V = 10L, R = 0.0821 atm•L/mol•K, and T = 20°C

First, convert the temperature to kelvin by adding 273.15. That's 293.15.

Now, modify the equation to solve for mols. That's n = PV/RT.

Input your values:

n = (12atm)(10L)/( 0.0821 atm•L/mol•K)(293.15K)

n = 4.985953116mol

Round to 2 significant figures to get 5.0mol

(I don't know if you usually do rounding so you may want to keep the answer exact)
