Question

Calculate the mass of 12.044 into 10 to the power 25 molecules of oxygen

Answer 1

Hi, consider the answer given below

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

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

6.022 x 10^23 molecules = 16g

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

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

= 3200g

I hope this will help you
