    Answer:

    2.31 * 10 ^ 19

    Step-by-step explanation:

    Take the number of kilograms  per liter and multiply by the number of liters

    3.5×10^−2 * 6.6×10^20​

    The coefficients get multiplied and the exponents add

    3.5 * 6.6   * 10 ^ (-2+20)

    23.1 * 10 ^ 18

    This is not scientific notation since 23.1 is greater than or equal to 10 so we move the decimal 1 place to the left and add 1 to the exponent

    2.31 * 10 ^ 19
