Question

if the weight of 5.6litres of a gas at stp is 11 grams the gas is​

Answer 1

Answer:

5.6L weighs 11g

5.6×4L will weigh 11×4g

ie., 22.4L will weigh 44g

ie., mass of 1 mol of gas is 44g

ie., the molar mass of the gas is 44g

Therefore the gas must be carbon dioxide(molar mass 44g)

NOTE..... 1mol of any gas occupies 22.4 L at STP
