Question

What is the mass of 12.044 into 10 to the power 23 number of O2 molecules

Answer 1

Answer:

Hi, consider the answer given below

Explanation:

You need to appreciate the fact that 6.022 x 10^23 molecules of oxygen atom weighs 16 g.

Therefore applying this to the calculation of this question we say that

6.022 x 10^23 molecules = 16 g

therefore 12.044 x 10^25 molecules is equivalent to what mass

(12.044 x 10^23) x 16/(6.022 x 10^23)

= 3200 g
