Question

11.11g of urea dissolve in 100g of water .find molarity​

Answer 1

moles of urea = 11.11/60 = 0.18

volume of water = 100ml because density = 1g/cc

volume of urea = mass / density

= 11.11/1.32 = 8.41ml

total volume = 108.41ml

molarity = moles /volume in litre

= 0.18 /108.41×10^-3 = 1.6Molar
