AP CHEM-URGENT PLEASE
could you please check my work? thanks. For the reaction between reactants A and B below, if 4.925 moles of A is placed into a flask with excess B it is found that the amount of A remaining after 6.85 seconds is 2.737 moles. 2A (g) + B (g)-----> 3 C (g) a. find the rate of ...

The amount of solute in 1L of 1.80M solution would be the same as that in 1.80/8.00L of the 8.00M solution. So, take 0.225L of the 8M, and fill the flask to 1L.

Since these mols are in 1.00L, mols = M. .........2SO2 + O2 ==> 2SO3 E........0.250..0.853...x Kc = (SO3)^2/(SO2)^2(O2) Substitute and solve for x.
