Question

the molecular weight of green vitrol is M0 .the weight of 10^-3 NA molecules of it is​

Answer 1

Answer:

Mo mg

Explanation:

No.of moles = 10^-3 Na/Na = 10^-3

Mass = 10^-3 Mo g = Mo mg (convert to milligrams)

Answer 2

Answer:

The answer is M0 mg

Explanation:

Given:

Molecular weight of green vitriol = M0

Weight of 10^-3 NA molecules = ?

(Note: NA is the Avagadro number)

No of moles = M0 x 10^-3 x NA/ NA = 10^-3 (As NA in the numerator and NA in the denominator get cancelled)

= 10^-3

Weight = M0 x 10^-3 g

Now, to convert it to mg, we multiply by 1000

=> M0 x 10^-3 x 1000 = M0 mg (10^-3 will be cancelled by 1000)

Therefore, the final answer is M0 mg
