Jul 9, 2014 · The hydrogen ion concentration is the same as the concentration of the acid because HCl is a strong acid and dissociates as follows: HCl -> H^+ + Cl^- (notice the 1:1 ratio of HCl and H^+) A 1M HCl solution has a pH of 0 A 0.1M HCl solution has a pH of 1 a 0.01M HCl solution has a pH of 2 This video discusses additional examples Noel P.

Oct 26, 2015 · Given the relative abundance of the following naturally occurring isotopes of oxygen: O-16: 99.76%, O-17: 0.037%, and O-18: 0.204%, how would you calculate atomic mass? Chemistry Matter Atomic Mass 1 Answer

Mar 22, 2016 · Here's what I got. !! EXTREMELY LONG ANSWER !! You're titrating hydrochloric acid, "HCl", a strong acid, with sodium hydroxide, "NaOH", a strong base, so right from the start you should know that the pH at equivalence point must be equal to 7. Hydrochloric acid and sodium hydroxide react in a 1:1 mole ratio to form water and aqueous sodium chloride "HCl"_text((aq]) + "NOH"_text((aq]) -> "NaCl ...

The titration of an impure sample of KHP found that 36.0 mL 0.100 M NaOH was required to react completely with 0.765 g of sample. What is the percentage of KHP in this sample? The titration of 20.0 mL of an unknown concentration #H_2SO_4# …

Oct 7, 2014 · You start by determining the empirical formula for the compound. Determine the mass in grams of each element in the sample. If you are given percent composition, you can directly convert the percentage of each element to grams. For example, a molecule has a molecular weight of 180.18 g/mol. It is found to contain 40.00% carbon, 6.72% hydrogen and 53.28% oxygen. Convert the percentages to grams ...

Nov 23, 2016 · 2/5 is already a fraction. It represents having 2 pieces out of a possible 5. If, by chance, you are seeking the decimal representation of this fraction, you can convert easily by simply dividing 5 into 2: 2-:5<=>5)bar2.00 " "0.4 5)bar2.00 " "20 " "bar" " " "0 2/5 in decimal form is 0.4, or 40%. (Example: scoring 2 out of 5 on a quiz is a score of 40%.)

Jul 30, 2016 · We can perform limited arithmetic on it: If a is any ordinary Real number, then a + oo = oo + a = oo If a is any ordinary non-zero Real number, then a*oo = oo*a = oo. So for example 5/0 = 5*1/0 = 5*oo = oo But expressions like 0*oo have indeterminate value. The expression 0/0 is still indeterminate too.
