Question

If one microbe has a mass of 2.63 x 10⁻²⁰ grams, what is the mass of 100 microbes?

A) 2.63 x 10⁻¹⁸ grams
B) 26.3 x 10⁻¹⁹ grams
C) 2.63 x 10⁻¹⁹ grams
D) 2.63 x 10⁻²¹ grams

Answer 1

The mass of 100 microbes, given that one microbe has a mass of 2.63 x 10⁻²⁰ grams, is 2.63 x 10⁻ⁱ⁸ grams.

Step-by-step explanation:

If one microbe has a mass of 2.63 x 10⁻²⁰ grams, then the mass of 100 microbes can be calculated by multiplying the mass of one microbe by 100. This gives us:

Mass of 100 microbes = 2.63 x 10⁻²⁰ grams x 100 = 2.63 x 10⁻²⁰ x 10² grams = 2.63 x 10⁻ⁱ⁸ grams

The correct answer is A) 2.63 x 10⁻ⁱ⁸ grams.
