At constant temperature and pressure, 5.0 l of so2 is
combined with 3.0 l of o2 according to the equation:
2 so2(g) + o2(g)  2 so3(g)
after so3 formation is complete, what is the volume of
the mixture?
(a) 5.5 l (b) 6.0 l (c) 6

What is the subscript for oxygen in its molecular formula

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?
