M r (aspirin) = 180, M r (NaOH) = 40 (atomic masses: C = 12, H = 1, O = 16, Na = 23) Therefore the reacting mass ratio is 180g aspirin reacts with 40g of sodium hydroxide. The titration was 16.45 cm 3, so, converting the cm 3 to dm 3, the mass of NaOH used in the titration = 4.00 x 16.45/1000 = 0.0658g, so we can scale this up to get the mass of aspirin titrated, therefore the mass of aspirin titrated = 0.0658 x 180 / 40 = 0.296g

Mar 15, 2014 · Write the balanced equation for the reaction of acetylsalicylic acid and sodium hydroxide? ... CH3CO2C6H4COOH + NaOH --> CH3CO2C6H4CO2- Na+ + H2O.

Write the balanced molecular equation for the neutralization reaction between H3PO4 and NaOH in aqueous solution. Phases are optional.

Sep 19, 2014 · In order to find the number of moles of NaOH, we multiplied the moles of our known substance, HCl, at .001 moles, by the molar ratio between HCl and NaOH in their balanced chemical equation. In the equation, they both have a coefficient of 1, so the molar ratio is one.

M r (aspirin) = 180, M r (NaOH) = 40 (atomic masses: C = 12, H = 1, O = 16, Na = 23) Therefore the reacting mass ratio is 180g aspirin reacts with 40g of sodium hydroxide. The titration was 16.45 cm 3, so, converting the cm 3 to dm 3, the mass of NaOH used in the titration = 4.00 x 16.45/1000 = 0.0658g, so we can scale this up to get the mass of aspirin titrated, therefore the mass of aspirin titrated = 0.0658 x 180 / 40 = 0.296g

Al 2 (SO 3) 3 + NaOH → Na 2 SO 3 + Al(OH) 3 The equation given above can be balanced by the Hit and trial method. First we balance the Na atoms. There are 2 Na atoms in the right hand side of the equation .so we balance the equation as Al 2 (SO 3) 3 +2 NaOH → Na 2 SO 3 + Al(OH) 3 Then we balance the Al atoms. write a balanced equation for the decomposition of aspirin essay write a balanced equation for the decomposition of aspirin writing service, you can be sure to get credible academic aid for a reasonable price, as the name of our write a balanced equation for the decomposition of aspirin website suggests.

Show your calculations for the mass of aspirin that reacted in each of the two trials based on the amount of NaOH used. Show your calculations for the average mass of aspirin in a tablet of aspirin. Show your calculations for the percentage of an aspirin tablet that is aspirin. Aspirin tablets are manufactured to contain 325mg of aspirin. --- coefficient of Ba(OH) 2 in balanced chemical equation Note that the above 2:1 ratio result because the M a V a is TWICE as big as the M b V b at neutralization. Drop the 2/1, do a little cross-multiplying and dividing and you get this:
