Question

Calculate the number of moles in 170g of ammonia nh3

Answer 1

Answer:

mole = weight /Molecular Weight

mole = 170/17

• 10mole

Answer 2

Answer:

10 moles

Explanation:

Number of moles present = weight in grams / moleculer weight of the compound

here -

weight in grams = 170 (given)

molecular weight of NH3 - 14 (molecular weight of N) + 3 (molecular weight of hydrogen*3) = 17

= 170/17 = 10

- therefore 10 moles is present in 170 grams of NH3 (ammonia)
