• 4 g of NaOH (40 g/mol) is dissolved in water to make 500 mL of solution. Its molarity is NEET level
• A solution contains 46 g of ethanol (46 g/mol) and 36 g of water (18 g/mol). The mole fraction of ethanol is NEET level
• A 500 g sample of water contains 2.5 mg of fluoride ions. The concentration in ppm (by mass) is NEET level
• 18 g of glucose (180 g/mol) is dissolved in 250 g of water. The molality of the solution is JEE Main level
