Answer:
The density of muffin is 0.2 g/ cm³.
Explanation:
Given data:
Mass of muffin = 100 g
Volume of muffin = 500 cm³
Density of muffin = ?
Solution:
Density is equal to the mass of an object divided by its volume.
Formula:
d = m/v
Now we will put the values in formula.
d = 100 g/ 500 cm³
d = 0.2 g/ cm³
The density of muffin is 0.2 g/ cm³.
