How many carbon atoms are in my sample
1 answer:
The number of atoms that are present in 24g Carbon sample is
An atom can be regarded as the basic building block of chemistry and it is the smallest unit.
The Relative Molecular Mass of Carbon is known to be (12 g)
The Mass of the item was given as 24 g
Then we can find the Moles as ( 24g Carbon sample/24 g) = 2
Then the Number of atoms can be calculated as the
( Avogadro Number*Moles)
Therefore, the number of atoms that are present in 24g Carbon sample is 12.044*10^23

The energy transferred is given as the product of power and time. The 1.4 kW kettle with boiled water produces 378 kJ of energy.
<h3>What is energy?</h3>Energy is the quantitative property that determines the work done by the body in the form of heat and light.
The image showing the kettles with time and power is attached below.
Given,
Power of the kettle = 1.4 kW
Time taken = 4.5 minutes
If power = energy ÷ time
Then, energy = power × time
= 1.4 × 0.075
= 0.105 KWh
Therefore, 0.105 kWh or 378KJ is the energy transferred.
