Q4/ Calculate the volume and weight of concentrated MgCl2.6H2O with a concentration of 95% by weight and a density of 4.52g/mL that is needed to prepare 450mL of the 3M solution. If you know the Atomic weights: Mg= 24.3, Cl= 35.5, H=1, O=16 Q5/ 38.2g NaHCO, is dissolved in a 1080g water. Calculate the formal, weight percent, and mole Fraction. The volume of the solution 400 mL? If you know the Atomic weights: Na = 23, H=1, C=12, O=16
