B. When numbers are very small or very large, it is convenient to either express the value in scientific notation and/or by using a prefix with the unit.

A pain-relieving pill has a mass of 0.005g. Express the pill’s mass in grams using scientific notation or in milligrams.

  • A. 48 m because all sides are equal and you multiply 12 by 4.

    B. 1 g = 1000 mg

    ___ _______

    0.005 mg = x mg

    Cross multiply.

    x mg = 5 g

    The answer is 5mg

  • Because a square has four sides of equal length, the perimeter is

    12 m+12 m+12 m+12 m=48.0 m

  • Squares have four sides of equal length, therefore:

    Perimeter = 4 x 12 m = 48 m

    0.001 g = 1 mg => 1 g = 1000 mg

    Convert grams into milligrams by multiplying the value (in grams) by 1000, therefore:

    0.005 g x 1000 = 5 mg

    I hope I’ve helped you learn how to do any similar questions by yourself, not not just given you the answers 🙂

  • A.

    P = 48 m


    0.005 g = 5 mg

  • Use either an integer, decimal number, or scientific notation for the numeric portion of your answer. Do not use calculations or functions.

  • 48m


  • 48.0m
