Calculate the density; D= mass/ volume 1) A student measures the mass of an 8 cm3

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

•The Lewis structure, also known as the Lewis dot diagram, Lewis dot formula, Lewis dot structure, electronic dot structure, or electronic Lewis dot structure (LEDS), is a diagram that shows the relationship between molecular atoms. And individual pairs of electrons are present in the molecule.
