Answer:

0.0512 mol

Explanation:

Molarity of a substance , is the number of moles present in a liter of solution .

M = n / V

M = molarity  

V = volume of solution in liter ,

n = moles of solute ,

From the question ,

Moles of hydrochloric acid is to be calculated ,

Molarity of hydrochloric acid = 1.75 M

Volume of hydrochloric acid = 29.3 ml

1 ml = 1 / 1000 L

Volume of hydrochloric acid = 29.3 ml /1000 = 0.0293 L

Using the above formula to calculate moles -

M = n / V

n = M * V

n = 1.75 M * 0.0293 L = 0.0512 mol

A 1. 00 ml sample of an unknown gas effuses in 11. 1 min. an equal volume of h2 in the same apparatus under the same conditions
Damm [24]

A 1. 00 ml sample of an unknown gas effuses in 11. 1 min. an equal volume of h2 in the same apparatus under the same conditions effuses in 2. 42 minutes then the molar mass of the unknown gas is 41.9.

Molar mass of H2 = 2

Molar mass of unknown gas = ?

rate 1 = 11.1

rate 2 = 2.42

<h3>What is graham law? </h3>

Graham's law states that the rate of diffusion or effusion of a given gas is inversely proportional to the square root of its molar mass.

By apply graham law

Rate1/rate2 = sqrt(MW2/MW1)

[\frac{rate1}{rate2} ]^{2} = \frac{MW2}{2} \\\\\\mw= 2[\frac{11.1}{2.42} ]^{2} \\\\= 20.97 X 2 \\\\= 41.9

Thus, we found that the molar mass of the unknown gas is 41.9.
