Answer: Molarity of in the original sample was 1.96M
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
Now put all the given values in the formula of molarity, we get
Thus molarity of in the original sample was 1.96M
<u>Answer:</u> The below calculations proves that the rate of diffusion of is 0.4 % faster than the rate of diffusion of
<u>Explanation:</u>
To calculate the rate of diffusion of gas, we use Graham's Law.
This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:
We are given:
Molar mass of
Molar mass of
By taking their ratio, we get:
From the above relation, it is clear that rate of effusion of is faster than
Difference in the rate of both the gases,
To calculate the percentage increase in the rate, we use the equation:
Putting values in above equation, we get:
The above calculations proves that the rate of diffusion of is 0.4 % faster than the rate of diffusion of
