85.50 mL of 0.0815 M sodium hydroxide is reacted with 8.15 g oxalic acid as shown in the reaction below. What mass of the excess reactant remains after the reaction is complete? H2C2O4(s) + 2 NaOH(aq) ? Na2C2O4(aq) + 2 H2O(l)
NaOH (aq) are required to neutralize 25.0 mL of HCl (aq). Calculate the concentration of the hydrochloric acid solution.
Value of E: 1.3 g x 1 mole/100.09=1.29 x 10-2 moleCaCO3 Using the value in your answer to question E., calculate the number of moles of HCl that two TUMS
A second 50ml aliquot was brought to a pH of 10 with an HCN/NaCN buffer, which also served to mask Cd2+; 11.56 ml of EDTA solution were needed to titrate the Pb2+. Calculate the percentage of Pb and Cd in the sample.
Starting from the ideal gas equation, show how you can calculate the molar mass of a gas from knowledge of its density.
which is to say that potassium iodide is added to the sodium chloride as a nutrient. When a 4.2962 g sample of table salt was analyzed by precipitating the halides with silver nitrate, 10.4192 g of a miture of AgCl and AgI resulted.
