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.
