Commercial perchloric acid (100.46 g/mol) 71% (w/w) with specific gravity of 1.67 was diluted by taking 30.00 mL portion of this acid and diluting with 70.00 mL of water. The final molar concentration after dilution is: Please fill in the space witha numerical value with two digits or two decimal places without units

An impure sample contains 0.74 g of impurities and 4.55 g of benzoyl acid. The sample is dissolved in 100 mL of water and heated. The solution is then cooled. How many grams of the impurity will crystallize when the solution has cooled? The solubility of the impurity and benzoic acid in cold and hot water are given below: Compound/ Cold water solubility/Hot water sol Ben acid/ 0.42 g per 100 mL/ 5.79 g per 100 mL Impurity/ 0.61 g per 100 mL/ 4.62 g per 100 mL   Are the crytals produced pure benzoic acid?

Calculate equivalent weight of unknown acid using the following information: Mass of unknown acid= 0.1725 g Volume of 0.1015 N NaOH used to titrate acid= 8.3 mL

Biological studies have found that aqueous solutions containing as little as 28 µg of allicin per milliliter inhibit bacterial growth.

How am I supposed to calculate the mass of the final solution?

Trying to determine concentration of sucrose in soda equation for standard curve:  y= 0.0186x+1 volume: 50 mL cola density = 1.08412 g/mL mass = 54.2060 g actual concentration (given) M of sucrose:  0.659449 M How would i determine: concentration of cola, Molarity of sucrose, percent mass of sucrose and mole fraction of sucrose given the information?
