X= (3*2)(31.75)/(2*17)3*31.75/17
=5.603g H2
Answer: 5.603g H2
It’s all quite simple actually considering the fact the M(NH3) = 14 + 1*3 = 17g/mol
And M(H2) = 2*1 2g/mol
So 3H2 + N2 >> 2NH3
Givin that Xg is 31.75g

Pretty sure the answer is A, but you probably shouldn't use Brainly to answer test questions.
5.426 x
molecules are there in a deep breath of air whose volume is 2. 35 L at body temperature 36 C and a pressure of 740 torr.
Explanation:
Data given:
volume V = 2.35 L
Temperature T = 36 Degrees or 273.15 + 36 = 309.15 K
pressure P = 740 torr OR 0.973 Atm
R = 0.08205 L atm / mole K
n (number of molecules of gas)= ?
The formula used will be
PV = nRT
Putting the value of given variables in above equation:
n = 
= 
= 0.0901 moles
According to Avagadro' s law that gases at equal volume, temperature and pressure contains same molecules.
number of molecules:
number of moles x avagadro number
0.0901 x 6.02 x 
= 0.54 x 
= 5.426 x
molecules.
