Question

mass of one molecule of a substance is 3.4x10^-22 . calculate its molecular mass​

Answer 1

Answer:

200

Explanation:

I assume that the mass is in g.

one mol = 6.022×$10^{23}$ molecules

the required molecular mass:

3.4×$10^{-22}$×6.022×$10^{23}$

=20.4748×10

=200 (corr. to 3 sig. fig.)
