Using the information I’ve provided, calculate the molarity of the HCl concentration using the information provided. Here’s the reaction:
HCl + NaOH > H2O + NaCl
Volume of HCl: 20.0 mL
Concentration of HCl: UNKNOWN
Know concentration of NaOH: 0.100 M
Titrate end point or total of NaOH volume dispensed: 48.6mL

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
