Homework Statement
k so we are doing a lab on determining the chemical formula of a hydrate (CuSO4.xH20) wat i need help on is these following questions:
1. suppose the hydrate was heated too quickly and some of it was lost as it spattered out of the container explain how this would affect
a) the calculated percent by mass of water in the compound.
b) the molecular formual you determined.
wat i think da answer to
1a) wuld bee that mass wuld change because some of solution spattered and since it was heated too quickly da water is not completely evaporated
and for 1b) da molecular formula wuld change because thur wuld be more water molecules...
nd other question i don't get is that
2.how wuld u determine the molecular formual of CuSO4.xH20
based on this information
Mass of empty beaker or evaporating dish - 185.6g
Mass of beaker or evaporating dish + hydrated copper (II) sulfate. 190.1g
Mass of beaker or evaporating dish + anhydrous copper (II) sulfate. 191.2g
do u hafto find X first ?
