The molar mass of a gas that moves 1.25 times as fast as CO2 is 28.16 g.
<h3>
Molar mass of the gas</h3>
The molar mass of the gas is determined by applying Graham's law of diffusion.
R₁√M₁ = R₂√M₂
R₁/R₂ = √M₂/√M₁
R₁/R₂ = √(M₂/M₁)
where;
- R₁ is rate of the CO2 gas
- M₁ is molar mass of CO2 gas
- R₂ is rate of the second gas
- M₂ is the molar mass of the second gas
R₁/1.25R₁ = √(M₂/44)
1/1.25 = √(M₂/44)
0.8 = √(M₂/44)
0.8² = M₂/44
M₂ = 0.8² x 44
M₂ = 28.16 g
Thus, the molar mass of a gas that moves 1.25 times as fast as CO2 is 28.16 g.

IT will be Refraction of light
Solutions with pH less than 7 are acidic in nature.
Therefore, a substance of pH 6 will be a weak acid.
Zinc (Zn) always has a +2 charge. It is one of the exceptions.
