Calculate the number of grams of oxygen gas in a 24L container at STP

romanna [79]

There are 34 g of oxygen in the container.

We can use the<em> Ideal Gas Law</em> to solve this problem.

$pV = nRT$

But $n = \frac{m}{M}$ , so

$pV = \frac{m}{M}RT$ and

$m = \frac{pVM}{RT}\\$

STP is 0 °C and 1 bar, so

$m = \frac{\text{1 bar} \times \text{24 L} \times 32.00 \text{ g}\cdot\text{mol}^{-1}}{\text{0.083 14 } \text{bar}\cdot\text{L}\cdot\text{K}^{-1}\text{mol}^{-1}\times\text{273.15 K} } = \textbf{34 g}\\$

Write an inequality that is true only for temperatures (t)(t)left parenthesis, t, right parenthesis that are higher than the boi

katrin2010 [14]

Inequalities are mathematical expressions that include more than one mathematical value for which they are true. In this case, all temperatures greater than the boiling point of water are satisfactory for the expression. The boiling point of water is 100 °C, so the inequality becomes:

t > 100 °C
