Question 13
No of moles of glucose = 0.5 x 0.4 = 0.2 Moles
Hence 0.2 Moles of glucose present at 0.5 L of 0.4 M glucose.
Question 14
Volume of NaI = 0.405 x 1000 / 0.724 = 559..39 ml
Hence 559.32 ml of 0.724 M NaI contains 0.405 mol.
Question 15
Mass of Mg(NO3)2 = 45 gm
Molar mass of Mg(NO3)2 = 148.30 g/mol
Moels of Mg(NO3)2 = 45 gm / 148.30 g/mol = 0.30343 Moles
Volume of Mg(NO3)2 = 0.30343 x 1000 / 0.32 = 948.25 ml
948.25 ml of 0.32 M of Mg(NO3)2 contains 45 gm of Mg(NO3)2
