Explain how you would make 500ml of a 0.100 m naoh solution

Molar mass NaOH = 23+16+1=40 g/mol

0.100 M = 0.100 mol/L

500 ml=0.500 L

0.500L*0.100 mol/L=0.0500 mol NaOH we need to prepare 500 ml solution

0.0500 mol NaOH*40g/1mol=2 g NaOH we need to prepare 500 ml solution

we need 2 g NaOH, dissolve it in small amount of water, and dilute it with water up to 500 mL
