Question

calculate the mass of 12.004 ×10^25 molecules of oxygen​

Answer 1

hi, consider the answer given below

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

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

6.022×10^23 molecules = 16g

therefore 12.044×10^25 molecules is equivalent to what mass (12.044×10^23) × 16/6.022×10^23)

= 3200g
