1000 is the missing exponent
First, let's figure out how many cups of cheese we need for one dozen people.
There are 12 people in one dozen.
<u>3 cups of cheese </u> = <u>x cups of cheese</u>
6 people 12 people
<u>
</u>
that means we will need 6 cups of cheese for 12 people, or one dozen.
However, we want to make nachos for two dozen people.
6 cups of cheese for one dozen x 2 dozen = 12 cups of cheese
<em>You need 12 cups of cheese to make nachos for two dozen people. </em>

Answer:</h3>
4.42×10^34 molecules/min
<h3>
Step-by-step explanation:</h3>
Multiply the various factors, along with the unit conversion (60 s/min).
... (3.35×10^25 molecules/L) × (2.2×10^7 L/s) × (60 s/min)
... = (3.35×2.2×60)×10^(25+7) molecules/min
... = 442.2×10^32 molecules/min
... ≈ 4.42×10^34 molecules/min
