9. Density
1. What is the density of an object with a mass of 2g, and a volume of 18 cm3?
D=m/v
D=2g/18 cm3
D=0.11g/cm3
2. The density of Mercury is 14g/cm3, what is the volume of 42g of mercury?
D=m/v v *D=m/v *v
v=m/d v=42g/14/cm3
v=3 mL

10. Density Density = Mass/Volume
1. What is the density of an object with a mass of 2g, and a volume of 18 cm3?
D=0.11g/cm3
2. The density of Mercury is 14g/cm3, what is the volume of 42g of mercury?
v=m/d
v=3 mL

11. Density What is the mass of 50 mL of benzene? D=m/v m=D X v
m=.87g/mL X 50 cm3
m=43.5 g/mL
2. What is the volume of 20 g of methanol?
D=m/v v=m/d v= 20g/0.79 g/mL v=25.32g/mL

D=2g/18 cm3
D=0.11g/cm3
2. The density of Mercury is 14g/cm3, what is the volume of 42g of mercury?
D=m/v v *D=m/v *v
v*D/D=m/D
v=m/D v=42g/14 cm3
v=3 cm3

14. Density
