Question

4) A 4.00 L balloon is filled with 0.297 moles of helium gas with a pressure

of 0.910 atm. Calculate the temperature, in Kelvin, of the gas. (KEEP 3 SIG

Answer 1

Answer: 149

Step-by-step explanation:

Using the ideal gas equation; PV = nRT

P= Pressure = 0.910 atm, T= Temperature = ?

V= Volume = 4.0L R = Gas constant = 0.08206 L.atm/mol/K

n = number of moles = 0.297

Making 'T' the subject of the formular, we have;

T = P V/ n R = 0.910 x 4 / 0.297 x 0.08206

= 149
