Forty grams of silicon carbide (sic) boiling chips with a density of 3.2 g/cm3 are added to 600 ml of toluene with a density of 0.9 g/cm3. what is the concentration of sic chips in mg/l?

The concentration of SiC chips is 65,306.122  mg/L.

Explanation:

Mass of silicon carbide ,m= 40 g

Density of silicon =

Volume of silicon carbide = v

Volume of toluene = V = 600 mL = 0.6 L

Volume of solution = v + V = 0.0125 L + 0.6 L =0.6125 L

The concentration of SiC chips in mg/L:

m = 40 g = 40,000 mg

(1 g = 1000 mg)
