I'd be interested in knowing how you came up with that answer. 8 hr and 24 min, according to my calculation is [(8*60)+24/60] = 8.4 hrs. k = 0.693/t1/2 = 0.693/2.8 = 0.2475 ln(No/N) = kt I took No = 100 (an arbitrary number) Solved for N k from above t = 8.4 Solving for N...

There is some moisture in the air as water vapor(gas). By the way water vapor is single H2O molecules with a mass of 18 grams/mole. Air is mostly Nitrogen, N2, with a molecular mass of 14*2 = 28 grams per mole so air with water vapor in it tends to be less dense than the ...

Fixing typo and expanding y = k x put in your first point 8 = -2 k solve that for k so k = -4 NOW any other point on this line satisfies y = -4 x so put in 12 for y 12 = -4 x x = -3 as you know from "cross multiplying"
