An atom has a nucleus filled with neutrons and protons, and electrons circle the outside of it.
Answer:
48.6 g
Explanation:
Given data:
Length of one side = 3 cm
Density of cube = 8.1 g/cm³
Mass of cube = ?
Solution:
First of all we will calculate the volume of cube.
V = length × height × width
V = 3 cm × 3cm× 3cm
V = 27cm³
Now we will determine the mass by using density formula.
d = m/v
d = density
m = mass
v = volume
8.1 g/cm³ = m/ 27 cm³
m = 8.1 g/cm³ ×27 cm³
m = 48.6 g
Gas --> separated particles, usually a great amount away from each other
Liquids --> particles are closer together but not always touching
Solids --> particles are solidly packed together, not one is distant
hope this helped, have a fantastic night/day/morning :)
This is just addition. Put 2140.56 on top, line up 9.3456 under it appropriately. Doing this will give you the answer: 2149.9056
