Answer: A. inconsistent data
Indeed, using inconsistent data in a research or more to support an argument will only jeopardize its validity. A scientific argument supported by inconsistent data will be considered invalid and unreliable. That's why there are several scientific ways on data gathering.
1 mol CuSO₄·5H₂O ----------- 5 mol H₂O
0,25 mol CuSO₄·5H₂O ---- Xmol H₂O
X = 5×0,25 = 1,25 mol H₂O
Empirical formula is the simplest ratio of whole numbers of components making up a compound.
empirical formula can be calculated as follows
C H O
mass 12.0 g 2.00 g 5.33 g
number of moles
12.0 g / 12 g/mol 2.00 g / 1 g/mol 5.33 g / 16 g/mol
= 1.00 mol = 2.00 mol = 0.333 mol
divide by the least number of moles
1.00 / 0.333 2.00 / 0.333 0.333/ 0.333
= 3.00 = 6.01 = 1.00
the number of atoms
C - 3
H - 6
O - 1
empirical formula is C₃H₆O
