Point "C" is correct and all the remaining are false.
Note, HomeAtomic and HeteroAtomic compounds are the types of compounds, but not homogenous and heterogenous.
Explanation:
a. CGS system: centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time
b. SI system: metre as the unit of length, the kilogram as the unit of mass, and the second as the unit of time
Answer: The name of this Hydrate is magnesium sulphate monohydrate.
Explanation:
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
a) If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of = 87.0 g
Mass of = 13.0 g
Step 1 : convert given masses into moles
Moles of =
Moles of =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For =
For =
Hence the empirical formula is
Thus the name is magnesium sulphate monohydrate.
