Answer:
volumme =0.36 ml
Explanation:
total heat required can be obtained by using following formula
.......(1)
where,
m - mass of water,
C - specific heat capacity of water and = 4.184 j g^{-1} °C
- total change in temperature. = 10°C
The density of water is 1 g/cc. hence, 200 mL of water is equal to 200 g
putting all value in the above equation (1)
q = 200*4.184* 10 ° = 8368 J.
Therefore total number of moles of ethanol required to supply 8368 J of heat is
The molar mass of ethanol is 46 g/mol.
The mass of ethanol required is 46* 0.006117 = 0.28138 g
The density of ethanol is 0.78 g/ml.
The volume of ethanol required is
