A container holds 6.4 moles of gas. Hydrogen gas makes up 25% of the total moles in the container. If the total pressure is 1.24

Degger [83]

The partial pressure of hydrogen is 0.31 atm

calculation

find the number of hydrogen moles the container, that is

25/100 x 6.4 =1.6 moles of hydrogen

find the partial pressure for hydrogen in 1.6 moles

that is 6.4 moles= 1.24 atm
1.6 moles= ?

by cross multiplication

1.6moles x1.24 atm/ 6.4 moles= 0.31 atm

Suppose a 10.0 mL sample of an unknown

mote1985 [20]

The concentration of HCl is equal to 2.54mol/L.

<h3>Mole calculation</h3>

To solve this question, one must use the molarity calculation, which corresponds to the following expression:

$M = \frac{mol}{v}$

Thus, to find the molarity of the sample, the following calculations must be performed:

$V_f = 10ml + 625ml = > 635ml$

$\frac{0.004mol}{xmol} =\frac{1000ml}{635ml}$

$x = 0.00254 mol$

So, 0.00254 moles were added per 10ml, so we can do:

$\frac{0.00254mol}{xmol}= \frac{10ml}{1000ml} \\x = 2.54mol/L$

So, the concentration of HCl is equal to 2.54mol/L.
