The relation between force, mass of an object and its acceleration is given by following equation
F = mass of object X acceleration
The unit of Force is Newton (N)
unit of acceleration is ms⁻²
unit of mass if Kg
[all these are SI units]
Mass of object =
mass of sprinter =
2.1 x 10²²atoms
Explanation:
Given parameters:
Mass of silver = 3.78g
Unknown:
Number of atoms of silver = ?
Solution:
To solve this problem, we first find the number of moles of the silver from the given mass.
Number of moles =
Molar mass of Ag = 108g/mole
Number of moles = = 0.035mole
Now;
A mole of any substance contains 6.02 x 10²³ atoms
0.035 moles of Ag will contain 0.035 x 6.02 x 10²³ = 2.1 x 10²²atoms
