22. Mass=Force/acceleration or M=F/a. So the force of this equation would be 88N and the acceleration would be 4m/s^2 so the mass in the problem would be 22.
Answer:
1.48381734165x 10²⁵ molecules
Explanation:
1 grams CuNo3 is equal to 0.0011897028836018 mole.
x = 5.5 moles
x = 5.5 x 1/0.0011897028836018 = 5.5/0.0011897028836018
4623.003grams
the molar mass of cuno3 =187.56 = 6.02 x10²³
4623.003g = x
187.56x = 4623.003 x 6.02 x10²³ = 27830.47806 x10²³ = 1.48381734165x 10²⁵

Scientist Evidence Model
Dalton Gases indivisible, solid and spheres
J.J Thomson Deflected beam Negative charges evenly scattered
through positively charged mass of
matter.
Rutherford Deflection of alpha atomic model
particles passing
through the gold foil
The emboldened words are the answer.
- John Dalton proposed the first model of the atoms by his works on gases. He postulated the Dalton's law of partial pressure.
- He suggested that gases are made of tiny particles called atoms.
- J.J Thomson proposed the plum pudding model of the atom in which the charges are evenly scattered through the positively charged mass of matter.
- The gold foil experiment by Rutherford brought the atomic model of the atoms in the front-light.
- The model suggests a small positively charged center which the mass of the atom.
- The outer space is occupied by the electrons.
