$9.38\times10^{33}$

Step-by-step explanation:

Given: Molecules in a liter of water = $3.35\cdot10^{25}$

A certain river discharges about $2.8\cdot10^8$ liter of water every second.

Molecules in river = $3.35\cdot10^{25}\times2.8\cdot10^8$

$=3.35\cdot2.8\cdot10^{25}\cdot10^8\\\\= 9.38\times10^{25+8}\ \ \ \ [a^m\cdot a^n=a^{m+n}]\\\\= 9.38\times10^{33}$

Hence, there are $9.38\times10^{33}$ does the molecules in river per second.
