How many grams of oxygen gas are there in a 2.3 L tank at 7.5 atm and 24 C

22.6 g

Explanation:

First we use the PV=nRT equation:

We input the data:

And solve for n:

Then we convert 0.708 moles of oxygen gas (O₂) to grams, using its molar mass:

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
