Question

calculate the mass of sulphur atom at N. T. P which occupy a volume of 11.2litre​

Answer 1

As per the mole concept 1 mole stp occupies 22.4 ltr but at ntp it occupies same

22.4/2 =11.2 which 1/2 mole of sulphur

mass of sulphur is 32/2 is 16 g

Answer 2

the gram atomic mass of sulphur in NTP is 32 gram

so in NTP the volume of 32 gram sulphur is 22.4 litre

so the mass of sulphur which occupy a volume of 11.2 litre is16( gram)
