Answer:
The concentration of SiC chips is 65,306.122 mg/L.
Explanation:
Mass of silicon carbide ,m= 40 g
Density of silicon = [tex]d =3.2 g/cm^3[/tex]
Volume of silicon carbide = v
[tex]Density=\frac{Mass}{Volume}[/tex]
[tex]d=\frac{m}{v}[/tex]
[tex]v=\frac{40 g}{3.2 g/cm^3}=12.5 cm^3=0.0125 L[/tex]
[tex]1 cm^3=0.001 L[/tex]
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)
[tex]=\frac{40,000 mg}{0.6125 L}=65,306.122 mg/L[/tex]
