45.6 grams of CH4 is placed into a 275 mL container at 55.00C. What is the pressure inside the container in atm?

Given-

Mass of CH4 - 45.6 grams

Molar mass of CH4 - 16.04 g/mol

volume - 275mL

Temperature- 55°C

Solution,

moles of methane (CH4) n = 45.6/16.04

= 2.84 moles

Using Formula,

Pv = nRT

P*275 = 2.84*8.314*55

P = 1298.64/275

P = 4.72 Atm.

Answer - The pressure inside the container in atm is 4.72.
