QUESTION: Problem 38P
A 355-mL container holds 0.146 g of Ne and an unknown amount of Ar at 35°C and a total pressure of 626 mmHg. Calculate the moles of Ar present.
ANSWER:
Solution 38P
Here, we have to calculate the moles of Ar.
Step 1 of 5
First let's calculate the moles of Neon
Moles of Neon =
Given amount of Ne = 0.146 g
Molar mass of Ne = 20.18 g/mol.
= = 7.23 x 10-3 mol.
Therefore, moles Neon is 7.23 x 10-3 mol.
