The moles which were measured out is calculated using the following formula
moles = mass/molar mass
molar mass of CuBr2.4H20 = 63.5 Cu + ( 2 x79.9) br + ( 18 x4_) h20 = 295.3 g/mol
moles is therefore= 5.2 g/ 295.3 g/mol= 0.0176 moles
Answer:
one reason is, Water is a very good liquid for cooling things down, for one thing there is plenty of it and it has also got a high specific heat capacity. This means that it can absorb a large amount of heat energy without getting too hot.
will not heat up or cool down very fast
Water has a high value of latent heat of vapourization so it has cooling properties.
hope this helps you. :)
