D= m/v —> density= mass: volume |
Equation used to calculate density |
|
|
10.0 g for every 10.0 cm cubes |
Is the density of water |
|
|
Solve this equation |
16.52 g divided by 2.26 cm cubes equal _____ density |
7.3 g/centimeters cubes=D |
|
Solve this problem 16.2g/2.26 |
7.32g/cm cubes=D |
|
|
163g divided by 50.0cm cubes |
D=3.26 g/cm |
