Calculate the molar mass of 20 L of gas weighing 23.2 g at STP. |
|
Answer» Solution :Molar MASS = `(" Weight of the substance X Molar VOLUME")/("Volume of the substance at STP")` Molar volume at STP = `2.24 xx 10^(2)m^(3)` = 22.4 L (or) 22400 cc. Molar mass of the GAS at STP = `(23.2xx22.4)/20 ` = 25.984 g . |
