Calculate the residence time of sodium. fill in the blanks. use t= m/f mass (m) flow rate (f) ton ton/year sodium 2.8 x 10^13 3.5 x 10^5 zach is investigating the residence time of sodium in sea water. according to zach's data table, the residence time of sodium written in scientific notation is x 10 years.

8.0 * 10^ 7 years

Explanation:

You just need to use the given equation with the two data also given.

1) Data:

m = 2.8 * 10^ 13 ton
f = 3.5 * 10^5 ton / year

2) Formula:

T = m/f

3) Solution

Subititute the values for the variables:

T = [2.8 * 10^ 13 tons ] / [3.5 * 10^ 5 ton / year] = 0.8 * 10^ 8 = 8.0 * 10^ 7 years.

8.0 * 10^7 years.
