These nutrient classes can be divided into macronutrients (nutrients required in large quantities) and micronutrients (nutrients required in tiny quantities). Carbohydrates, proteins, lipids, fiber, and water are macronutrients, whereas vitamins and minerals are micronutrients.
Molar mass NaOH =23+16+1=40 g/mol
<span> 0.100 M= 0.100 mol/L
</span>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
