Answer:
Atomic mass of N relative to H is 13.9.
In periodic table mass of N is around 14 RAM
Explanation:
1 mol of ammonia has 1 mol of N, and 3 mole of H
NH₃
1 mol of H weighs 1 g, so the mole of H, present in ammonia are:
1.712 g / 1 g/m = 1.712 mole
Since the ratio is 1:3
1.712 mole/3 = 0.57 mole of N are present in the amonia
To calculate the atomic mass of N relative to H, let's consider it as molar weight.
Molar weight = mass / mole
7.933 g / 0.57 mole = 13.9 g/m
Answer is: Louis Pasteur (1822-1895) disproved spontaneous generation. He boiled liquid with proteins and other nutrients in S-neck flasks and regular flask to kill all microorganism present. In regular flask liquid showed changes when exposed to air and in S-neck flack there was no change (microorganism can not getting in the flask because the S- neck). When he removed S-neck, liquid changed because microorganisms came in liquid.
Pasteur showed it was not the air itself but particles within the air that had microorganisms.
