Answer:-
0.883 m
Explanation:-
Molality= Moles per Kg of solvent.
Molar mass of ethylene glycol= 62.07 g/ mol.
Number of moles of ethylene glycol= 82.2g / (62.07 g/mol)
= 1.324 moles
Density of water = 1 g/ml = (1/1000kg)/ (1/1000litre)
= 1 Kg / litre
Mass of 1.5 litre of water = 1.5 litre x 1 kg / litre
= 1.5 kg
Molality of ethylene glycol = 1.324 moles/1.5 kg
= 0.883 m
Answer:
They have the same number of electron energy levels.
They transition from a metal to noble gas.
Explanation:
Periods in the periodic table of elements refer to elements in the same row. All the elements in a certain row of the periodic table;
have the same number of electron energy levels.
transition from a metal to noble gas.
High energy waves have short wavelengths and thus high frequencies as a result.
I think it’s b?! have a good day!
