A.) Is CuSO4 soluble in water? How about FeSO4?
B.) What is the molar ratio between Fe and H20?
(A)Yes CuSO4 is soluble in water completly . FeSO4 also soluble in water.
(B) Molar mass of Fe = 55.85 g/mol
Molar mass of H2O = (2xAt.mass of H ) + At.mass of O
= ( 2x1) + 16
= 18 g/mol
So the molar ratio between Fe & H2O is = 55.85 : 18

AgBr is a sparingly soluble salt with a molar solublity of about 7x107 Min pure water. How would you expect the solubility to change if AgBr is dissolved into a solution of 1.0M AgNO3? O Solubility will be the same Solubility will be decreased O Solubility will be increased
What is the difference between how lipid soluble drugs and water soluble drugs get excreted by the kidney? Can they both be excreted by the kidneys and why?
What is the difference between fat-soluble and water-soluble vitamins in deficiency and toxicity levels? How do deficiencies and toxicities occur for each?
A student is given a sample of CuSO4(s) that contains a solid
impurity that is soluble and colorless. The student wants to
determine the amount of CuSO4 in the sample and decides to use a
spectrophotometer. First, the student prepares a calibration graph
by measuring the absorbances of CuSO4(aq) solutions of known
concentrations. The graph is shown below.a) (a) The student dissolves the entire
impure sample of CuSO4(s)CuSO4(s) in enough distilled water to make
100.mL100.mL of solution. Then the student...
