(1.20 x 10^8g +9.7 x 10^7g)/(3.04 x 10^5L)
%281.20+%2A+10%5E8+%2B9.7+%2A+10%5E7%29%2F%283.04+%2A+10%5E5%29
adjust the top for the same power of 10
%281.20+%2A+10%5E8+%2B0.97+%2A+10%5E8%29%2F%283.04+%2A+10%5E5%29
combine like terms on the top **** add 1.20 to 0.97 = 2.17
%282.17+%2A+10%5E8+%29%2F%283.04+%2A+10%5E5%29
%282.17%2F3.04%29%2A%2810%5E8%2F10%5E5%29
%280.7138%29%2A%2810%5E3%29
adjust to standard form
%287.138%29%2A%2810%5E2%29 = 7.138 x 10^2 grams per liter
