Answer:
P = 2.18 atm
Explanation:
The strategy here here is to use the ideal gas law
PV = nRT
since we know the temperature, volume and the n, the number of moles is mass/MW, and R is the gas constant 0.08205 LatmK⁻¹mol⁻¹:
MW HI = 127.91 gmol⁻¹
P = ( mass / MW ) x R x T / V
P= (50.0 g / 127.91 gmol⁻¹ ) x 0.08205 LatmK⁻¹mol⁻¹ x 340 K/ 5.00 L
P = 2.18 atm
( rounded to three significant figures which is the number of significant figures for temperature, mass and volume )
