What is the volume of 0.80 grams of O2 gas at stp?

sergey [27]

<u>Answer: </u>The volume occupied by $O_2$ at STP is 0.56 L.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Given mass of oxygen = 0.80 g

Molar mass of oxygen = 32 g/mol

Putting values in above equation, we get:

$\text{Moles of oxygen}=\frac{0.80g}{32g/mol}=0.025mol$

<u>At STP:</u>

1 mole of a gas occupies 22.4 L of volume.

So, 0.025 moles of oxygen gas will occupy = $22.4\times 0.025=0.56L$ of volume.

Hence, the volume occupied by $O_2$ at STP is 0.56 L.

Compare the strength of intermolecular forces in no2 to the strength of intermolecular forces in n2

matrenka [14]

N2 is non-polar molecules,
NO2 is polar molecules that have slightly positive charge on N and slightly negative on O, so <span>intermolecular forces are stronger in NO2</span>
