Question

weight of 5.6 litres of a gas at STP is 11 grams,the gas is
1)phospine
2)phosgene
3)nitric oxide
4)Nitrous oxide


with process please

Answer 1

The correct answer is PHOSPINE.

Process - Standard temperature and pressure -- usually abbreviated by the acronym STP -- are 0 degrees Celsius and 1 atmosphere of pressure. Parameters of gases important for many calculations in chemistry and physics are usually calculated at STP. An example would be to calculate the volume that 56 g of nitrogen gas occupies.


wt of 22.4 lit gas=(22.4/5.6)*11=44g

wt of N2O = 14*2+16=44g

All the best....!
