1.	Mass of one molecule of a substance is 3.4x10^-22 . calculate its molecular mass
Answer» ONG>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.)

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

Answer» ONG>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.)
