How many grams of HCl(s) are there in 300 mL of 4.50% w/v HCl(aq) solution?

None

Citric Acid C6H8O7 a natural food preservative accounts for the tartmess of citrus fruits. About 730 g of this substance can be dissolved in water making a liter of solution. Howe ver only about 1.5% of it dissociaes. As such it would be considered a     acid. What is the molarity (M) of this solution ? MM (citric Acid)=192 g/mol

(a) How many moles of hydrogen peroxide are supplied by 0.75 mL of a 30.0% (w/w) aqueous solution of hydrogen peroxide? The density of 30.0% hydrogen peroxide is 1.10 g/mL. (b) If the concentration of hydrogen peroxide was reported instead as 30.0% (w/v), how many moles of hydrogen peroxide would 0.75 mL contain?

What volume (in mL) of concentrated hydrochloric acid is necessary to prepare 10 mL of 1:1 (v/v) solution?

What is Molarity of a 10.00% (v/v) acetic acid ? Density of pure acetic acid is 1.05 g/mL.
