How many grams of BCl3 are needed to produce 30.0 g of HCl(aq)

A solution is prepared by dissolving 4.40 g of KSCN in enough water to make 340 mL of solution. What is the concetration (molarity) of the solution?

What is the concentration (in molarity units) of a solution which is prepared by dissolving 4.94 g of NaCl in enough water to make a 210.0 mL of solution?

Draw the product(s) of the following reactions. CH3 H₂C-C-CEC-H OH 1. BH3/THF 2. H₂O₂/ aqueous NaOH • You do not have to consider stereochemistry. Separate multiple products using the + sign from the drop-down menu. • You do not have to explicitly draw H atoms. • If no reaction occurs, draw the organic starting material.

A sample of 1.975 g oxalic acid dehydrate (H2C2O4 . 2H2O) was dissolved in enough water to make a 250.0 mL solution. What is the concentration of oxalic acid in the solution?In solid form, the dihydrate crystal lattice contains two water molecules for every oxalic acid molecule. The water molecules must be included as part of the molar mass. The molar mass of H2C2O4 * 2H2O is 126.064 g/mol. Oxalic acid is a diprotic acid (H2A). Write the balanced reaction for aqueous oxalic acid reacting with aqueous potassium hydroxide. If 20.00 mL of the oxalic acid solution described above is placed in a flask and then titrated with 0.1525 M potassium hydroxide, what volume of the potassium hydroxide solution would be required for a complete reaction?

If 230 mL of H2O is added to 20.0 mL of 12 M HCl, what is the final concentration of the solution?
