Your solution needs to have a concentration of 0.6M (mol/L)
You are using a flask of 100 mL, thats 1/10th part of a liter.
So you divide 0.6M by 10 $\to$ 0.06 mol in 100 mL

Now you need to calculate how many grams of NaOH equals 0.06 mol.
To do this you need the molecular weight of NaOH, this is 39,99711 g/mol.
