A gas at standard temperature and pressure was measured as having a mass of 1485 grams (g) in a volume of 750 liters (L). Which
tangare [24]

Answer:

Here we will use the relation:

Density = mass/volume.

We know that:

Mass = 1485g

Volume = 750L

Density = 1485g/750L = 1.98 g/L

We do not have the options in order to select the correct one, but knowing this density, we can suppose the possible gases.

Two "common" gases with densities similar to this one are:

Carbon Dioxide, with d = 1.977 g/L

Dinitrogen Monoxide, with d = 1.977 g/L

In both cases, if we round up we will get the same density that we calculated at the beginning, so either of these can be the correct option.
