Chemistry

Use the density and molecular weight of limonene, linalool, andnonane to calculate the volumes of the compounds you will need tomake the stock solution of 50 nM. Also calculate the finalconcentration of those solutions after dilution.
Nonane: d = 0.718 g/mL, MW = 128.26, 99% pure
Limonene: d = 0.84 g/mL, MW = 136.24, 96% pure
Linalool: d = 0.861 g/mL, MW = 154.25, 97% pure.

Ans 1 purity 99 Thus actual amount of nonane in 0718 g sample 99 of 0718 g 071082 g So 1 ml of sample has 071082 g nonane Number of moles in 071082 g sample mass molecular mass 071082 g 12828 g mol1 00055411 moles 55411 x 103 moles sample 1 Stock 50 nM solution 50 x 108 M 50 x 108 moles in 1 L Now 1000 mL of stock has 50 nmoles solute sample 2 1 mL 50 nmoles 1000 mL 50 x 104 nmoles 50 x 1013 moles Preparing necessary dilution Since the concentration of the stock solution is very low we need to make two dilutions to make its preparation practically feasible Step 1 Take 1 mL of original sample in 1L standard volumetric flask and make the volume upto mark with distilled water This solution is 11000 diluted Thus concentration of this See Answer
