Answer:
no. of water molecules associated to each molecule of 
= 4
Explanation:
Mass of before heating = 19.8 g
Mass of after heating = 12.6 g
Difference in mass of before and after heating
= 19.8 - 12.6 = 7.2 g
Difference in mass corresponds to mass of water driven out.
Molar mass of water = 18 g/mol
No. of moles of water = 
Mass of obtained after heating is mass of anhydrous .
Mass of anhydrous = 12.6 g
Molar mass of = 125.9 g/mol
No. of mol of anhydrous = 
so,
0.1 mol of have 0.4 mol of water
1 mol of will have = 
Hence, no. of water molecules associated to each molecule of = 4

Answer:
Heat
Explanation:
In the iron where electric current is used to heat water, electrical energy is converted to heat energy which is boils the water to steam.
Electrical energy is due to the movement of current within a circuit. The heat produced by the electrical energy is transferred to the water.
This in turn forms steam which is used for the ironing processes.
Heat energy is generated when the average kinetic energy of the molecules in a system increase.
