Answer:
Molar mass of the unknown gas is 8.96g/mol
Explanation:
Hello,
According to Graham's law of diffusion, its states that the rate of diffusion of a gas is inversely proportional to the square root of its molecular mass
R = k (1/√(M))
R = rate of diffusion
M = molecular mass
R₁ / R₂ = √(M₂ / M₁)
R₁ = nitrogen = 68.3s
R₂ = unknown gas = 85.6s
M₂ = molecular mass of the unknown gas
M₁ = molecular mass of nitrogen = 14g/mol
68.3 / 85.6 = (√M₂ / 14)
0.8 = (√M₂ / 14)
Take square of both sides
0.8² = M₂ / 14
M₂ = 14 × 0.64
M₂ = 8.96g/mol
The molar mass of the unknown gas is 8.96g/mol

Answer:
Nitrogen.
Explanation:
Nitrogen is the gas that makes up the highest percentage of air.
Answer:The majority of chemical processes are reactions that occur in solution. Important industrial processes often utilize solution chemistry. "Life" is the sum of a series of complex processes occurring in solution. Air, tap water, tincture of iodine, beverages, and household ammonia are common examples of solutions.
A solution is a homogenous mixture of substances with variable composition. The substance present in the major proportion is called the solvent, whereas the substance present in the minor proportion is called the solute. It is possible to have solutions composed of several solutes. The process of a solute dissolving in a solute is called dissolution.
