Question

calculate the mass of 5 mole of ammonia​

Answer 1

Mass =17.031× 5= 85.155

Explanation:

mol=mass/molar mass

mass= mole × molar mass

Answer 2

Answer: 51g

Explanation:

Applying Avogadro law,

1 mole= mass/mol.mass of an element.

Given, 5 moles of NH3.

Hence,

5mol= mass/mol.mass of NH3

Mol. Mass of NH3= 14+3(1)

=17g

5mol=mass/17

5*17=mass

Hence, mass of ammonia= 85g.

Hope it helped you!!
