Answer:
The answer is
<h2>126.58 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
<h3>
</h3>
From the question
mass of alcohol = 100 g
density = 0.79 g/mL
The volume is
We have the final answer as
<h3>126.58 mL</h3>
Hope this helps you
The hydrate form of CuSO4 has 5 water molecules (CuSO4-5H20) copper (II) Sulfate pentahydrate or commonly known as blue vitriol.
To solve, the following molar masses are to be known.
CuSO4.5H2O (hydrate) - 249.7g/mole
CuSO4 (anhydrous) -159.6g/mole
Also there molar ratio of the hydrate and CuSO4 is 1.
the mass of the hydrate is to be divided by the molar mass of the hydrate then multiplied by the ratio (1) to get the moles of hydrate and multiplied by the molar mass of the anhydrous to get the mass in grams.
moles = (100g/249.7)*1 = 0.4 moles hydrate
grams = 0.4*159.6 = 64.9 grames hydrate
