Calculate the volume of ammonia gas produced at STP when 140g of nitrogen gas reacts with 30g of hydrogen gas.(atomic mass: N=14u,H=1u) how to do this?

1 Answer

Answer:

Ans:#color(red)((10×22.4L=224"L")#

Explanation:

Simply, the reaction is #N_2+3H_2=2NH_3#
#140g# #"N"_2# means #140/28=5# mol;
#30g# #H_2# means #30/2=15#mol
From 1 mol of #N_2# 2 mol #NH_3# is prepared in perfect presence of #H_2#
Hence, #10#mol of #NH_3# will be produced.
We know,1mol of any ideal gas at STP (#0^@ "C"# and #"1 atm"#) contains 22.4L of the ideal gas.

Produced ammonia is #224" L"#.
