A liter of water contains about 3.35•10^25 molecules. A certain river discharges about 1.8•10^8 litter of water every second. About how many molecules does the river discharge every minute. Write your answer in scientific notation.

[tex] \frac{3.35 \times 10^{25} molecules}{1 liter} \times \frac{1.8 \times 10^{8} liter}{1 second} \times \frac{60 second}{1 minute} = \frac{3.35 \times 1.8 \times 60 \times 10^{25+8} molecules}{1 minute} = 3.618 \times 10^{35} \frac{molecules}{minute} [/tex]
