Finding molarity when % by mass is known

[erjkism]

i need to find the molarity of acetic acid from this data:

CH3COOH (molar mass 60.05) (% by mass: 99.7) (density: 1.05 g/ml)

how do i do it??

Find out the mass in grams of 99.7 % of the compound and d = m/v and M = n/v. Hope that helps.

One more thing that I want to add to the previous post is that after you find the mass you should convert it to moles and apply it to the molarity formula.
