John measures the mass of a cup of chocolate milk and a glass of orange Juice. He places both containers on a balance scale. He observes that the scales tips fower towards the cup of chocolate milk. He concludes that the chocolate milk has a greater mass. What statement best describes the error in John's measurement? (2 points)
Only solids have mass so comparing the mass of two liquids is not possible.
John can only compare the mass of two liquids that are the same.
John has to pour each liquid into a container with the same mass and then compare them

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)
