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
