Question

the number of moles in 1.7g of ammonia is​

Answer 1

Answer:

please make me brainliest

Step-by-step explanation:

1 mole of the ammonia contains 6.022 × 10²³ atoms. ∴ 17 g of the Ammonia contains 6.022 × 10²³ atoms. ∴ 1 g of the ammonia contains (6.022 × 10²³)/17 atoms. ∴ 1.7 g of the ammonia contains (6.022 × 10²³) × 1.7/17 atoms.14

Answer 2

Answer:

6.02 × 10²²

Step-by-step explanation:

1.7 gram of ammonia ( molecular weight is 17g/mol) =

$= \frac{1.7g}{17g/mol} = 0.1 \: \: .mol$

So, the no. of molecule in 1.7 gram of ammonia is =

= 0.1 mol × 6.02 × 10²³ mol = 6.02 × 10²² molecules ans.

have an nice day ahead !!!
