Please show me how to solve this problem. I don'tunderstand very well.
I will give proper respect as soon as possible. PLEEEASE helpme!!! #3.5 With what mass of nitrogen would 1g of hydrogencombine to form ammonia NH3? [Hint: All you need to know is the ratio of the masses of theatoms concerned; you can find these masses, listed in atomic massunit, inside the back cover.] Atomic mass unit: 1u = 1/12m(12C atom) Book answer is 4.67g ( or more exactly, 4.63) #3.5 With what mass of nitrogen would 1g of hydrogencombine to form ammonia NH3? [Hint: All you need to know is the ratio of the masses of theatoms concerned; you can find these masses, listed in atomic massunit, inside the back cover.] Atomic mass unit: 1u = 1/12m(12C atom) Book answer is 4.67g ( or more exactly, 4.63)

Explanation / Answer

The molar mass of hydrogen M(H) = 1.00797 * 1 g/mol = 1.00797g/mol The molar mass of nitrogen M(N) = 14.0067 * 1 g/mol = 14.0067g/mol The molar mass of M(H3) = 3 * 1.00797 g/mol =3.02391 g/mol The amount of hydrogen in 1 g is 3.02391 g/mol The amount of nitrogen in x g is 14.0067 g/mol when 1 g of hydrogen combine to form ammonia then x = (14.0067/3.02391) = 4.63g
