1.	Calculate the volume in litres of 20 g of hydrogen gas at STP .
Answer» Solution :NUMBER of moles of hydrogen = `("mass of hydrogen")/("MOLECULAR mass of hydrogen in grams") = (20 g)/(2G) = 10` . `therefore` volume of hydrogen = number of moles `xx` STANDARD molecular volume `= 10 xx 22.4 = 224` litres .
