Answer:
Hi it is uhmm 1.59*10^-18
If you need explanation I would be happy to help!
The mass of the 30,000 molecules is [tex]1.59\times 10^{-18}[/tex]
Given that,
Based on the above information, the calculation is as follows:
[tex]= 30,000 \times 5.3\times 10^{-23}\\\\= 3\times10^4 \times 5.3\times 10^{-23}\\\\= 15.9\times 10^{-23+4}\\\\= 15.9\times 10^{-19}\\\\= 1.59\times 10^{-19}\times 10\\\\= 1.59\times 10^{-18}[/tex]
Therefore we can conclude that the mass of the 30,000 molecules is [tex]1.59\times 10^{-18}[/tex]
