Concentrated HCl has a molarity of 12.1M.

1. What volume of HCl (in mL) do you need to prepare 250.00 mL of 3.25 MM M HCl? in mL

can someone please show work I'm really struggling with this last question and please explain I'll really appreciate it!

According to the label on a bottle of concentrated hydrochloric acid, the contents are 36.0% HCl by mass and have a density of 1.18 g/mL.

1.) What volume of it would you need to prepare 671 mL of 2.80 M HCl? _____ML

a) Calculate the molarity of urea in a solution preparedbydissolving 80.0 mg of pure urea in enough water to make 5.00 mlofsolution. MM urea (CO(NH2)2) = 60.055g/mol.
