A student dissolved 1.625 g of pure acetylsalicylic acid in water and titrated solution to equivalence point using 88.43 ml of .102 M NaOH (aq) Assuming that acetylsalicylic acid has only one ionizable hydrogen calculate molar mass of acid
If I took 5mg of salicylic acid and added it to a 500mL volumetric flask and bringing it up to volume with a 0.1M NaOH solution what would be the concentration of this?
How many grams of NaOH are contained in 230.0 mL of a 0.800 M sodium hydroxide solution?
2I2 + N2H4 → 4HI + N2 a. How many grams of I2 are needed to react with 36.7 g of N2H4?
During a titration, the following data were collected. A 25 mL portion of a solution of an unknown monoprotic acid was titrated with 1.0 M NaOH(aq).
Estimate the average spacing between water molecules in liquid water by making use of 2 pieces of information: (a) liquid water has a density of 1 g/cm^3
Suppose four weighings of a crcucible were found to be 10.231 g, 10.278 g, 10.256 g, and 10.363. Obtain the average (mean) weight of the crucible
How much heat is required to warm 227 g of ice from -44.5°C to 0.0°C, melt the ice, warm the water from 0.0°C to 100.0°C, boil the water, and heat the steam to 173.0°C.
If a sample of 0.230 grams of KCN is treated with an excess of HCL, calculate the amount of HCN formed, in grams.
While in Europe, if you drive 107 km per day, how much money would you spend on gas in one week if gas costs 1.10 per liter and your car's gas mileage is 26.0.
What is the freezing point of a solution of 1.17 g of 1-naphthol, C10H8O, dissolved in 2.00 mL of benzene at 20°C? The density of benzene at 20°C is 0.876 g/mL. Kf for benzene is 5.12°C/m, and benzene's normal freezing point is 5.53°C.
A solution is made by mixing exactly 500 mL of 0.180 M NaOH with exactly 500 mL of 0.100 M CH3COOH. Calculate the equilibrium concentration of the species
Hydrogen was cooled from 150 c to 50 c. It's new volume is 75 ml. What was the original volume?
