Chemistry
I would use P = (756-23.8)/760 = 0.963 atm; however, going with your number will still get close to the right answer. PV = nRT or n = PV/RT = 0.995*0.205/0.8206*298 n = 0.00834. You had to use some other (incorrect) version of n = PV/RT. Then n = grams/molar mass or molar mass...

(5000 - x).12 + x(.10) = 568 (5000).12 - (x).12 + x(.10) = 568 600 - .12x + .1x = 568 subtract 600 from both sides -.12x + .1x = -32 -.02x = -32 divide both sides by -.02 x = 1600 3400 at 12% and 1600 at 10%

A Texas Aggie buys 12 cans of dehydrated water. The cans weigh an average of 63.46g each before the dehydrated water is removed. If the density of pure distilled water is 0.9979 g/mL and each can has a volume of 3.154L, what is the total mass of the cans AFTER the removal of ...

Physics
In a mass spectrometer, singely ionized carbon-12 (normal carbon of atomic mass number 12) has a radius of curvature of 9 cm. What would be the radius of curvature of singely ionized carbon-14, assuming equal velocities? (A) 12.3 (B) 10.5 (C) 7.71 (D) 3.58

Trigonometry
This is the ambigious case, there are 2 cases possible sinA/23.9 = sin 12.1/15 sinA = .33399 angle A = 19.5° or 160.5° case1: A = 19.5, B=12.1, then C=148.4 c/sin148.4 = 15/sin12.1 c = 37.5 case2: A= 160.5, B=12.1, then C = 7.4° c/sin7.4 = 15/sin12.1 c = 9.23

Math Analysis (similar to my previous question)
A + B = < 30,000 A > = B B = < 12,000 B return > A return In order to maximize money we have to invest it. The rate of retern is highest with the B bond so, A + 12,000 = 30,000 B = 12,000 A = 18,000

Chemistry (Making sure
I didn't check the math and I don't remember all of the specific heats or heat of fusion, but the method looks ok to me. For Step 1, I didn't know if the 12 degrees was supposed to be a negative. You do this one or two ways. The first one is to reason that you are ...
