Chemistry
1 answer:
Anastaziya [24]3 years ago
8 0

Answer:

This compound is Ammonium Sulphide and has molar mass 68 g/mol.

Explanation:

  • Molar Mass : It is the mass of 1 mole of the substance and in grams.Its units are gram/mole.
  • It is numerically equal to mass of the substance in atomic mass units

How to calculate Molar mass :

(NH_{4})_{2}S = 2(atomic\ mass\ of\ N + 4\times mass\ of\ H ) +atomic\  mass\ of\ S

(NH_{4})_{2}S = 2(14 + 4(1) ) + 32

(NH_{4})_{2}S = 2(14 + 4 ) + 32

(NH_{4})_{2}S = 2(18) + 32

(NH_{4})_{2}S = 36 + 32

(NH_{4})_{2}S = 68 grams/mole

Molar mass of Ammonium sulphide is 68 g/mol

geniusboy [140]

Answer:

A (contains most of the mass of the atom)

Evidence has it that a proton is about 2000 times as massive as an electron.

And there is usually multiple protons and neutrons in the nucleus

From what I just said, you can say that B is wrong

C however is also wrong because protons have a +charge and neutrons are neutrle which means you always have a charge > (greater than) 0

And D is wrong because electrons (which are not in the nucleus) have a neg charge. and protons have a + charge and are in the nucleus

So your answer is A

Hope it helped
