Chemistry, Urgent!
Down to moles oxygen = 0.6 is ok. 0.6 moles oxygen means how many moles X2O3 were formed? 0.6 moles O2 x (2 moles X2O3/3 moles O2) = 0.6*2/3 = 0.4 moles X2O3 moles = grams/molar mass rearrange to molar mass = g/moles = 40.8/0.4 = 102 so molar mass X2O3 = 102. So molar mass is...

Ri = (102-92)/(31.9-10.3) = 0.463 Ohms, internal resistance. E = 102 + 10.3*0.463 = 107 Volts. Or E == 92 + 31.9*0.463 = 107 Volts.

errrgg..i meant i figured out #2 i need help with #1. My formula is as instructed. B=a/p (Base=amount/percent) My answer is: B=102.00/0.15 B=6.80 so the regular prices is 102.00+6.80=108.80 Is that correcT?

algebra
You can find the sum of the first 102 counting numbers using Gauss's method, namely: "the sum of the first n counting numbers is n*(n+1)/2" whether n is odd or even. For n = 102, the sum is 102*103/2=10506. So divide 10506 by 5220 to get a quotient of 2, with a remainder of 66...

Yes, there's a typo. It's actually 3+4+4+4+4+5+6=30 and there's a graph included in this problem but I don't know how to show the graph so that was why I just described how it looked like with all the vertices and degrees of each. Let me list those vertices and edges: MCS100 ...

I am curious what college considers this to be college level. The product of mass and distance from the fulcrum is the same on both sides, if the seesaw is balanced. Thus 31 * 3.6 = 78 * X Solve for X, which will be Arthur's distance in meters.

Apply the law of conervation of linear momentum before and after the drop, along the direction of motion. This does not seem like college level physics. In any case, you should be able to take it from there.
