Any would be greatly appreciated!! Thanks
In an experiment 25 g of HCL (g) is dissolved in H2O to make 100mL of an acidic solution. Assuming that the acid completely ionized, what is the pH of the solution?..........................-log[25/(0.1*36)]
What mass of styrene (mm= 104.1) will contain 4.5E20 molecules of styrene?........................7.78E-2g
A liter of solution contains 0.00001 mole of HCL. What is the pH of this solution?.........................5.0
A compund consisting of C, H, & O is known by quanitative analysis to have 38.71% C & 9.68% H. What is the empirical formula of this compound?.........................CH3O
