Calculate the density; D= mass/ volume 1)
A student measures the mass of an
8 cm3 block of brown sugar to be 12.9 g.
What is the density of the brown sugar?
2) A chef fills a 50 mL container with 43.5 g of
cooking oil. What is the density of the oil?

density of sugar = 1.6 g/cm³

density of oil = 0.87 g/mL

Explanation:

1)

Given data:

Mass of object = 12.9 g

Volume of object = 8 cm³

Density of brown sugar = ?

Solution:

Formula:

d = m/v

d = density of object

m = mass of object

v = volume of object

Now we will put the values in formula.

d = 12.9 g/ 8 cm³

d = 1.6 g/cm³

2)

Given data:

Mass of oil  =  43.5 g

Volume of container = 50 mL

Density of oil = ?

Solution:

Formula:

d = m/v

d = density of oil

m = mass of oil

v = volume of oil

Now we will put the values in formula.

d = 43.5 g/ 50 mL

d = 0.87 g/mL
