Answer:
3 mole
Explanation:
2 moles of Ag give 1 mole of Mg(NO3)2
5 moles of Ag will give 5×1÷2 of Mg(NO3)2
=2•5 =3
Answer:
Explanation:
1. Calculate the molal concentration
The formula for the freezing point depression by a nonelectrolyte is
2. Calculate the moles of solute
3. Calculate the molecular mass
It is a Covalent bond because the electrons are shared between the two individual atoms. (Hydrogen is complete at 2 electrons)
