Answer:
1.806 x 10^24 atoms total
Explanation:
Answer:
Heat transferred, Q = 1542.42 J
Explanation:
Given that,
Mass of water, m = 30 grams
Initial temperature, 
Final temperature, 
We need to find the energy transferred. The energy transferred is given by :

c is specific heat of water, c = 4.18 J/g °C
So,

So, 1542.42 J of energy is transferred.
