Question

calculate the no of moles of 5.1g of nh3​

Answer 1

Answer:

1 mole of NH3 = 17 g

17 g - 1 mole

1 g - 1/17 mole

5.1 g - 5.1/17 mole = 3/10 mole

that's the answer mate..:)

Answer 2

Explanation:

the molar mass of NH3 will Be....

14+3 = 17

then the no Of mol. = given mass/molar mass

we get... 5.1/17 = 0.3 mole.

hope it helps you....
