To find the difference in mass between a grain of rice and a strand of hair, we subtract the mass of the strand of hair from the mass of the grain of rice.
Mass of grain of rice = 0.002 ounces
Mass of strand of hair = 2.17 * 10^(-5) ounces
Difference in mass = Mass of grain of rice - Mass of strand of hair
Difference in mass = 0.002 - 2.17 * 10^(-5) = 0.002 - 0.0000217
Since the difference is less than 1, we can express it in scientific notation:
Difference in mass = 1.9783 * 10^(-3) ounces
Therefore, a grain of rice is 1.9783 * 10^(-3) ounces heavier than a strand of hair.
