<u>Answer:</u> The number of atoms of bromine present in given number of mass is
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of bromine = 1.37 g
Molar mass of bromine = 79.904 g/mol
Putting values in above equation, we get:
According to mole concept:
1 mole of an element contains number of atoms.
So, 0.0171 moles of bromine will contain = number of bromine atoms.
Hence, the number of atoms of bromine present in given number of mass is
- Mass=m=750g=0.75kg
- Q=78.45\times 10^3J=78450J
- T_i=100°C
- T_f=?
- Specific heat capacity=c=4200J/kg°C
According to thermodynamics
