Explanation:

You will need to use the ideal gas equation and the molar mass of the nitrogen gas.

1. Calculate the number of moles of gas, using the molar mass.

Molar mass of nitrogen gas (N₂) : 2 * 14.0067 g/mol = 28.0134g/mol

number of moles = mass in grams / molar mass

number of moles = 100g / (28.0134g/mol) = 3.5697 mol

2. Calculate the temperature using the ideal gas equation:

a) dа ta:

p = 45,000Pa = 45. kPa V = 50 liter n = 3.5697 mol (calculated above) T = ? R = 8.3145 (liter. kPa) / (mol⋅K)

b) Formula and solution

pV = nRT T = (pV) / (nR) T = (45. kPa * 50 liter) / (3.5697mol * 8.3145 (liter. kPa) / (mol. K) T = 75.8K ≈ 76K
