Question

Calculate to three significant digits the density of sulfur hexafluoride gas at exactly 0°C and exactly 1 atm. You can assume sulfur hexafluoride gas behaves as an ideal gas under these conditions.

A. 1.73 g/L
B. 3.21 g/L
C. 4.34 g/L
D. 7.61 g/L

Answer 1

To calculate the density of sulfur hexafluoride (SF6) gas at 0°C and 1 atm, divide its molar mass by 1000 and use the ideal gas law equation. The density of SF6 gas at 0°C and 1 atm is approximately 6.14 g/L.

Step-by-step explanation:

The density of a gas can be calculated using the ideal gas law equation: density = (mass of gas)/(volume of gas). To calculate the density of sulfur hexafluoride (SF6) gas at 0°C and 1 atm, we need to know its molar mass. The molar mass of SF6 is 146.06 g/mol. Since density is measured in g/L and 1 L is equal to 1000 mL, we can convert the molar mass to g/L by dividing it by 1000. Therefore, the density of SF6 gas at 0°C and 1 atm is approximately 6.14 g/L.
