A closed flash contains 0.60 moles of xe, 0.50 moles of h2, and 0.40 moles ar. if the total pressure is 1.5 atm, what is the partial pressure of h2?

0.50 atm

Explanation:

Step 1: Calculate the total number of gas moles

The total number of moles is equal to the sum of the number of moles of each gas.

n = nXe+ nH₂ + nAr

n = 0.60 mol + 0.50 mol + 0.40 mol = 1.5 mol

Step 2: Calculate the mole fraction of hydrogen

The moe fraction of hydrogen is the quotient between the number of moles of hydrogen and the total number of moles.

ΧH₂ = 0.50 mol / 1.5 mol = 0.33

Step 3: Calculate the partial pressure of hydrogen

Given the total pressure (P) is 1.5 atm, we can calculate the partial pressure of hydrogen using the following expression.

pH₂ = P × ΧH₂

pH₂ = 1.5 atm × 0.33 = 0.50 atm

i think its 100

i hope this !
