Answer:
b
Explanation:
Atom is the smallest particle of an element
The density of the object is 19 g/cm³.
The mass of the object is 73 g.
The volume of the object is 3.8 cm³.
Density = mass/volume = 73 g/3.8 cm³ = 19 g/cm³
Answer:
A(yellow) = 52
Explanation:
A(yellow) = A(total) - A(red)
= 11×6 - 7×2
= 66 - 14
= 52
