Calculate to three significant digits the density of sulfur hexafluoride gas at exactly 15°c and exactly 1atm . you can assume sulfur hexafluoride gas behaves as an ideal gas under these conditions.

6.18 g/L

Explanation:

To calculate the density of gas, we use the equation given by ideal gas equation:

Number of moles (n) can be written as:

where, m = given mass

M = molar mass

where,

which is known as density of the gas

The relation becomes:

   .....(1)

We are given:

M = molar mass of =  146.06 g/mol

R = Gas constant =

T = temperature of the gas =

P = pressure of the gas = 1 atm

Putting values in equation 1, we get:

Thus density of sulfur hexafluoride gas at exactly 15°C and exactly 1atm is 6.18g/L
