Answer to Question #212705 in Organic Chemistry for Vicky

Question

A compound contains 12.8grams copper 6.4grams sulphur 12.8grams oxygen and 18grams of crystallisation find the simpless formulae of the compound

Answer 1

Divide the above with their molar mass

For

$Copper = \frac{12.8}{63.546}=0.2$

$Sulphur = \frac{6.4}{32.065}=0.2$

$Oxygen = \frac{12.8}{15.999}=0.8$

$Crystallisation = \frac{18}{18.01528}=0.999$

Ratio

$\frac{0.2}{0.2}=1, \frac{0.2}{0.2}=1, \frac{0.8}{0.2}=4, \frac{1.0}{0.2}=5$

$CuS4O_25H_2O$
