Question

Mass of a sample which is having 6.023 into 23 molecules of ammonia will be dash grams

Answer 1

Answer:

1 mole = 6.023 ×10^23 molecules and NH3 that is ammonia molecular weight is 17 g which is called as one mole so.......

Mass of sample having 6.023 ×10^23 molecules of ammonia will be 17g

I hope it helps......

Answer 2

It has a mass of 17 g.

Explanation:

The mass of any sample can be calculated from:

• the no. of particles that it contains
• the moles of the sample
• the volume that the sample occupies

In the given question mass is asked to be determined from the number of particles.

Thus, the no. of moles in the given sample

=  given number of particles/ Avogadro's number$(N_a)$

= 6.023$\times 10^{23}$ / 6.023$\times 10^{23}$

= 1 mole

1 mole of ammonia has a mass of 17 g (its molar mass).
