how to find molarity ratio of 0.58 g of H2O and 0.42 g of CuSO4?

Question

anonymous · Answer

molar ratio? or molarity ratio
if it is molar ratio, you simply convert the masses into moles and divide for a ratio
if it's molarity (concentration), you are missing information regarding the volume

yeah I know, but we did a lb making crystals with 50 mL of water but then we crushed up the crystals and evaporated the water by heating them so I can't really have volume

you just said 50mL of water tho, volume right there

anonymous · Answer

yeah when we made the crystals, then we got 1.00 g of the crystals ( CuSO4 + H20)crushed it up and heated it up so theres no more H20 so the 50 mLis not relevant anymore

anonymous · Answer

i guess then convert the masses to mols using molecular formula then divide by eachother for a ratio

anonymous · Answer

okay yeah that's what I was thinking since there's no way you could have a volume, thanks (:
