Suppose that an ant colony has 3 million ants.Each has a mass of fifteen-hundredths of a gram.What is the total mass of the entire colony of ants? A) 4.5 × 10³ B) 4.5 × 10⁴ C) 4.5 × 10⁵ D) 4.5 × 10⁶

Question

Quizplus · Accepted Answer

To find the total mass of the entire colony of ants, we need to multiply the number of ants with the mass of each ant.

Mass of each ant = 15/100 = 0.15 grams.

Number of ants = 3 million = 3,000,000

Total mass of the entire colony of ants = 0.15 x 3,000,000 
= 450,000 grams

We can convert grams to scientific notation by moving the decimal point to the left until we have a number between 1 and 10, and then multiplying by the appropriate power of 10.

450,000 grams = 4.5 x 100,000 = 4.5 x 10^5

Therefore, the answer is Choice C, 4.5 × 10^15.
