0.1 molar solution of acetic acid is used in laboratory practice. How many grams of acetic acid should be taken to obtain 100 ml of 0.1 molar solution?

A 0.1 molar solution is 0.1 mol of acetic acid in 1 liter. We have 100 ml = 0.1 l, so we need to take 0.1 * 0.1 = 0.01 mol.
The molar mass of CH3COOH is 60 g / mol. The mass of acid required to prepare our solution is 60 g / mol * 0.01 mol = 0.6 g.
