To find the total mass of the 50 ants, you can use the formula:
\[ \text{Total mass} = \text{Average mass per ant} \times \text{Number of ants} \]
If the average mass of one ant is given as \( x \) grams, then the total mass of the 50 ants would be:
\[ \text{Total mass} = x \times 50 \]
So, if you substitute \( x \) with the actual average mass of one ant, you can calculate the total mass.
For example, if the average mass of one ant is 3 grams, the calculation would be:
\[ \text{Total mass} = 3 \times 50 = 150 , \text{grams} \]
To provide an exact answer, please supply the average mass of one ant.
