Molar heat of solution? (1 Viewer)

Yo, i need help with question 35....littlehelp?

The values obtained would be lower than theoretical values because heat may have been lost to the environment (so, there would have been a lower increase in temperature, thus, lower molar heat of solution). Rather than using a plastic beaker, an aluminium can insulated with aluminium foil should be used as it can provide better insulation and will minimise the amound of heat lost to the environment.
