Question

calculate mass of one molecule of NH3​

Answer 1

Answer:

Moles of NH3 = given mass (?) / molecular mass = Number of molecules /NA( Avagadro number )

Mass (?) = 1 × 17 / 6.022 * 10^23

Mass of 1 molecule of NH3 = 2.82 *10^(-23 ) g

Answer 2

The mass of 1 molecule of ammonia is $2.82\times 10^{-23}g$

Explanation:

Molar mass is defined as the mass of 1 mole of a substance

We are given:

Molecules of ammonia = 1

Molar mass of ammonia = 17 g/mol

According to mole concept:

$6.022\times 10^{23}$ number of molecules are present in 1 mole of a compound

$6.022\times 10^{23}$ number of molecules of ammonia will have a mass of 17 grams

So, 1 molecule of ammonia will have a mass of = $\frac{17}[6.022\times 10^{23}}\times 1=2.82\times 10^{-23}g$
