If a compound contain 40% sulphur and 59% oxygen ,find its empirical formula.
2 answers:
Answer:
SO3
Explanation:
Data obtained from the question include:
S = 40%
O = 59%
To obtain the empirical formula, do the following:
Divide the above by their molar mass as shown below:
S = 40/32 = 1.25
O = 59/16 = 3.69
Next, divide by the smallest as shown below:
S = 1.25/125 = 1
O = 3.69/1.25 = 3
Therefore, the empirical formula is SO3
Answer:
SO3
Explanation:
According to the photo above
First you convert from percentage to decimal
Divide by the mass number
You divide the two by the smallest figure
Approximate
