Solved, Nevermind.
Chemistry
Part 1: Each molecule of NO2, nitrogen dioxide, consists of 1 atom of N and 2 atoms of O. If you have 0.155 g. of NO2, how many molecules of NO2 do you have ? 0.155gx46.0 = moles moles x 6.02 E23 = answer Part 1 Answer: 2030000000000000000000 Part 2: How many atoms of N do you...

20.0% acetone 18.0% Ethyl Alcohol 62.0% water You take the mL you're trying to find divided by the whole solution, then multiply by 100. For example, you have 50.0mL/250.0mL = 0.20 Take 0.20 x 100 and it will give you the percent.
