Unless otherwise instructed, you may use the periodic table in the Chemistry: question.
What is the molar mass of ammonia (NH,)?
o 15 g/mol
o 17 g/mol
42 g/mol
43 g/mol

17 g/Mol

Explanation:

To determine the molar mass of any compound, you have to add up the molar masses of every atom that make up the respective compound. In this case NH3 equals one nitrogen atom and three hydrogen atoms.

What does that mean? Ammonia's molar mass will be the sum of the molar mass of one nitrogen atom and 3 times the molar mass of a hydrogen atom.

Peroindic table:

N=14.0067 g/mol.

H=1.00794 g/mol

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

let that person have a turn to speak : )
