Question

How many NH3 molecules are found in 0.250 mol of NH3?

2.41 x 1024 molecules NH3 ,

4.26 x 1023 molecules NH3 ,

6.02 x 1023 molecules NH3 ,

1.51 x 1023 molecules NH3

Answer 1

Answer:

1.5 x 10(23)

Explanation:

no of moles x avagadro number

Answer 2

Answer:

In 1 mol no. of molecules of NH3

=

$6.022 \times 10 {}^{23} molecules$

So the no. of molecules found in 0.250 mol

$= 6.022 \times 10 {}^{23} \times 0.250 \\ = 1.51 \times 10 {}^{23} molecules$

So option d)

$1.51 \times 10 {}^{23} molecules$
