Density

Question 1

how do you calculate density if you HAVE mass and volume

Answer 1

D= m/v

Question 2

how to calculate volume

Answer 2

V= (l)x (w) x (h)

Question 3

what do i do if the mass is in kg

Answer 3

multiply it by 1000 to covert it into grams

Question 5

find the density
v= 15.0 mL
m=40.5 g

Answer 5

D=m/v
=40.5 g/ 15.0 mL
=2.7 mg/mL

Question 6

find the density
m=306.0 g
v=22.5 mL

Answer 6

D=m/v
= 306.0 g/ 22.5 mL
=13.6 g/mL

Question 7

how do i find the mass is i have density and volume

Answer 7

m= dxv

Question 8

how do i find the density of an irregular object

Answer 8

get a graduated cylinder and fill it up to your desired amount which will be V1 then put the object in. that will be V2 subtract V2 from V1 to find the overall volume. to find mass weigh the object and then canulate for density normally

Question 9

find the density
V1=45.50 mL
V2= 49.10 mL
m= 28.5 g

Answer 9

V final= V2-V1
= 49.10 mL - 45. 50 mL
= 36 mL
D= m/v
= 28.5g / 36
=792 mL/g
