A mixture of argon and neon has a measured gas density of 1.66 g / L at STP. Assuming ideal‑gas behavior, what is the average molar mass of the mixture?

The average molar mass of the mixture is 37.184 g/mole

Explanation:

Density of mixture = 1.66 g/L

1 mole of mixture contains 22.4 L by volume

Molar Mass of mixture = 1.66g/L × 22.4 L/1 mole = 37.184 g/mole

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
