A strand of hair has an average mass of 2.17 * 10 ^ - 5 ounces A grain of rice has an average mass of 0.002 ounces How much heavier is a grain of rice than a strand of hair? Express your answer in scientific notation point)

Answer 1

To find out how much heavier a grain of rice is than a strand of hair, we need to subtract the mass of the hair from the mass of the rice.

The mass of the rice is 0.002 ounces, and the mass of the hair is 2.17 * 10^(-5) ounces.

0.002 - 2.17 * 10^(-5) = 0.0019983

Now we need to express this answer in scientific notation. The number 0.0019983 can be written as 1.9983 * 10^(-3).

Therefore, a grain of rice is 1.9983 * 10^(-3) ounces heavier than a strand of hair.
