Answer: The molecular formula will be
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
Empirical weight of is
Molecular mass of compound is = 132 g
Now we have to calculate the molecular formula.
The molecular formula will be=
Answer:
Following are the solution to the given points:
Explanation:
In point a, the answer is only ions because of has a strong electrolyte.
In point b, the answer is the only molecules because of ethanol , it has a nonelectrolyte.
In point c, the answer is the few ions because of hydrocyanic acid HCN, which has a weak electrolyte.
Answer : The specific heat (J/g-K) of this substance is, 0.780 J/g.K
Explanation :
Molar heat capacity : It is defined as the amount of heat absorbed by one mole of a substance to raise its temperature by one degree Celsius.
1 mole of substance releases heat = 92.1 J/K
As we are given, molar mass of unknown substance is, 118 g/mol that means, the mass of 1 mole of substance is, 118 g.
As, 118 g of substance releases heat = 92.1 J/K
So, 1 g of substance releases heat =
Thus, the specific heat (J/g-K) of this substance is, 0.780 J/g.K
