Answer:
A gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure of 32.5 kPa.
<u>The pressure for oxygen is 3 kPa</u>
Explanation:
According to Dalton's Law of Partial Pressure total exerted by the mixture of non-reacting gases is equal to sum of the partial pressure of each gas.
So,
For , a gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure:

Answer:
6
Explanation:
This question is seeking for an equivalent of one expression. The first expression says 1/3 of 12, which means 1/3 × 12 = 4. To find 2/3 of a number that will give us 4, we say
Since; 1/3 of 12 is 4
Then, 4 = 2/3 of x, where x is the number, which when multiplied by two-third (2/3) will result to 4.
4 = 2/3 × x
4 = 2x/3
Cross multiply
2x = 3 × 4
2x = 12
x = 12/2
x = 6.
This means that; 1/3 of 12 = 2/3 of 6
