Question

The mass of a hydrogen atom is about 1.67E-24 grams. The mass of a plutonium atom is about 4.05E-22 grams. How many times

more grams is an atom of plutonium than an atom of hydrogen?
A. 2.43x10^2
B. 2.43x10^-2
C. 2.43x10^-3
D. 2.43x10^3

Answer 1

The answer would be C

Answer 2

2.43 × 102

Explanation:

Divide to find about how many times denser an atom of plutonium is than an atom of hydrogen.

First, write both numbers in scientific notation.

Now, divide using the quotient property of exponents.

So, an atom of plutonium is about 2.43 × 102 times more grams than an atom of hydrogen.
