Question

For example, if you have 13.9 liters of O2 gas, what would be the weight of this gas? (This question does not involve mentioning moles.)

Answer 1

To find the weight of the O2 gas, we can convert from liters to moles using the Ideal Gas Law and then convert from moles to grams using the molar mass of O2. The weight of 13.9 liters of O2 gas is 19.8 grams.

Step-by-step explanation:

To find the weight of the O2 gas, we need to use the molar mass of O2, which is 32 grams per mole. We can use the molar mass to convert from moles to grams. Given that we have 13.9 liters of O2 gas, we can use the Ideal Gas Law to convert from liters to moles:

13.9 liters O2 x (22.4 liters/mole) = 0.621 moles O2

Now, we can use the molar mass to convert from moles to grams:

0.621 moles O2 x (32 grams/mole) = 19.8 grams of O2

Therefore, the weight of 13.9 liters of O2 gas is 19.8 grams.
