A 2.4 L balloon holds 3.7 mol He. If 1.6 mol He are added to the balloon, what is the new volume?

Elanso [62]

For this question, lets apply Avagadro's law
when Pressure and temperature are constant, the volume occupied is directly proportional to the number of moles of gases.
$\frac{V}{n} = k$
where V-volume, n-number of moles and k - constant
Therefore at 2 instances
$\frac{V1}{n1} = \frac{V2}{n2}$
where V1 and n1 are for 1st instance
and V2 and n2 are for 2nd instance
therefore
$\frac{V1}{n1} = \frac{V2}{n2}$
V1 = 2.4 L
n1 = 3.7 mol
n2 = 3.7 + 1.6 = 5.3 mol
since more He moles are added at the 2nd instance its the sum of the moles.
V2 needs to be calculated $\frac{2.4}{3.7} = \frac{V2}{5.3}$
V2 = 2.4 x 5.3 / 3.7
= 3.4 L
Answer is 1st option 3.4 L

List or draw two ways to visually represent C6H14

KonstantinChe [14]

There are several ways to visually represent compounds. For this particular organic compound, we can use the skeletal formula and the expanded formula. The skeletal makes use of lines to show which atoms are bonded to each other. The expanded formula shows the species of the atoms and their bonding with other atoms. I have attached the two representations.
