Answer 2

I got the answer for you

Answer 3

So first use the formula Pv=nRT.
You are given Pressure, temperature, and gram of the element that you must use.
Standard temperature means it is: 273.15k and 1atm.
you need to convert 84g of Li into mole and solve for Liters which is:
84g of Li x 1mole of Li/ 6.941g Li (from periodic table)= 12.01 mole = n

Answer 4

Pv=nRT, v (in liters) = nRT / P ; (12.01mol)(0.08206)(273.15)/1 atm

Answer 5

R is a constant so it is always 0.082067 or .08206
