A student collected 50 ants. The average mass of one ant was 7.2X10 to the -2 power grams. What was the total mass (in grams) of the 50 ants?

Answer 1

To find the total mass of the 50 ants, you can multiply the number of ants by the average mass of one ant.

Given:

• Number of ants = 50
• Average mass of one ant = \( 7.2 \times 10^{-2} \) grams

Now, perform the multiplication:

\[ \text{Total mass} = 50 \times (7.2 \times 10^{-2}) \]

Calculating this:

\[ 50 \times 7.2 = 360 \]

Now, including the power of ten:

\[ 360 \times 10^{-2} = 3.60 \]

Thus, the total mass of the 50 ants is:

\[ \text{Total mass} = 3.60 \text{ grams} \]

So you would enter the answer as:

3.60
