A 22.4 L vessel contains 0.02 mol H2 gas, 0.02 mol N2 gas, and 0.1 mol NH3 gas. The total pressure is 700 torr. What is the partial pressure of the H2 gas

Partial pressure of is 98 torr

Explanation:

Mole fraction (x) of a gas in mixture = (no. of moles of the gas)/(total no. of moles of gases in mixture)

Here, total no. of moles of gases in mixture = (0.02 + 0.02 + 0.1) moles = 0.14 moles

So, mole fraction of gas in mixture,  

Let's assume all three gases and their mixture behaves ideally.

Therefore, in accordance with Dalton's law of partial pressure for ideal gases-

Here, and are partial pressure of and total pressure of mixture respectively.

So,        

the answer is definitely c.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
