Question

A gaseous compound composed of sulfur and oxygen has a density of 9.88 g/L at STP. What is the molar mass of this gas?

Answer 1

I am not sure hopefully you found your answer

Answer 2

The molar mass of this gas is 221 g/mol

Step-by-step explanation:

The relation between density and molar mass is : where P = pressure of gas = 1 atm (at STP) M = molar mass of gas = 32 g/mol d = density of gas = ? R = gas constant = T= temperature of gas = 273 K ( at STP) Thus the molar mass of this gas is 221 g/mol
