Answer:
There is a lot of empty space between them.
Explanation:
The kinetic molecular theory postulates that a substance is made up of tiny particles called molecules. The molecules of a gas are in constant random motion and collide elastically with each other. They also collide with the walls of the container.
The magnitude of intermolecular forces of attraction between gas molecules is very small. Hence gas molecules are largely apart with a lot of empty space between gas molecules.
Answer:
Climate change that is caused by humans
Answer:
3 g/cm³
Explanation:
Density= Mass divided by Volume
45÷15= 3
The answer is C. The number of moles of solute
Answer:
0.705 g/cm³
Explanation:
Step 1: define density
The (volumetric mass) density of a sample or substance, is this sample or substance its mass per unit volume and can be defined through following formula:
ρ = m/v
with ρ = density (kg/m³)
m = mass of the substance (kg )
v = volume (m3)
Step 2: change datat SI-units
10.0 cm³ = 10^-5 m³
7.05 g = 0.00705 kg
ρ = 0.00705 kg / 10^-5 m³ = 705 kg / m³
To convert this to g/cm³ we have to divide by 1000
ρ = 0.705 g/cm³
To control this we calculate 7.05g / 10cm³ = 0.705 g/cm³
The desnity of the alcohol is 0.705 g/cm³
