Problem Page A gas made up of atoms escapes through a pinhole 0.225 times as fast as H2 gas. Write the chemical formula of the g
Tcecarenko [31]
To determine what gas is this, we use Graham's Law of Effusion where it relates the rates of effusion of gases and their molar masses. We do as follows:

r1/r2 = √(M2 / M1)

Let 1 be the the unkown gas and 2 the H2 gas.

r1/r2 = 0.225
M2 = 2.02 g/mol

0.225 = √(2.02 / M1)
M1 = 39.90 g/mol

From the periodic table of elements, most likely, the gas is argon.

Answer:

The pH of the HCl solution is 3.9

Explanation:

Knowing the molar mass of HCl (36.5g/mol) it is possible to calculate the number of moles of HCl in the solution,

\frac{1.5x10^{-3}g}{36.5g/mol} = 4.1x10^{-5}moles of HCl

HCl is a strong acid and when added to water will form H+ and Cl-, thus the moles of HCl are equal to moles of H+ in 354 mL of water

\frac{4.1x10^{-5}moles }{354mL} x 1000= 1.16x10^{-4} M

The concentration of protons in the solutions is 1.16x10^{-4} M.

The expression used to calculate the pH is

pH = -Log ([H^{+}]) = -Log (1.16x10^{-4} M) = 3.9

Hence, the pH of the HCl solution is 3.9 and Pepsi has a pH of 3.4 approximately, so they have almost the same pH.
