A3.60 l gas sample is at a pressure of 95.5 kpa and a temperature of 25.0°c. if the gas sample weighs 6.10 g, calculate the molar mass of the gas.

Strategy of solution:

First, find the number of moles of the gas using the law pV = nRT. After that, find the molar mass by dividing the mass of the compound by the number of moles: molar mass = n / mm

Solution:

1)
p = 95.5 kPa
T = 25.0 + 273.15 K = 298.15 K
V = 3.60 l
R = 8.314 (l * kPa / K*mol)

=> n = pV / RT = [95.5 kPa * 3.60 l ] / [8.314 (l*kPa/K*mol) * 298.15 K] = 0.139 mol

2) mm = number of grams / number of moles = 6.10 g / 0.139 mol = 43.88 g/mol

43.9 g / mol (rounded to three significant figures)

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
