A sample of oxygen gas at a temperature and pressure has a density of 1.3gl. What is the density of propane(C3H8) gas under the same condition

Answer 1

To calculate the density of propane under the same conditions as oxygen, we can use the following formula:

Density of propane = (Molar mass of propane / Molar mass of oxygen) * Density of oxygen

First, we need to determine the molar mass of propane and oxygen:

Propane (C3H8): (3 * 12.01) + (8 * 1.01) = 44.07 g/mol (rounded to two decimal places)
Oxygen (O2): 2 * 16 = 32 g/mol

Now, we can calculate the density of propane:

Density of propane = (44.07 g/mol / 32 g/mol) * 1.3 g/L = 1.814 g/L

Therefore, the density of propane under the same conditions as oxygen is 1.814 g/L.
