At what temperature, in °C, would 1.50 moles of Ar gas at a pressure of 2.3 atm, occupy a volume of 25.8 L? Round your answer to the nearest hundredths. Don't forget to label your units. Show work.

I don’t know

Explanation:

B:H ratio is 1:3

Explanation:

The empirical formula is BH₃.

If you have 100 g of the compound.

Then you have 78.14 g B and 21.86 g H.

Now, we must convert these masses to moles and find their ratios.

From here on, I like to summarize the calculations in a table.

Element  Mass/g    Moles     Ratio     Integers

    B          78.14      7.2285    1                    1

    H          21.86    21.686      3.0001          3

The empirical formula is BH₃.
