Answer;
68.46 g of sucrose in 100mL
Solution and explanation;
Given 2L of 2 mol/L sucrose solution
Moles = concentration x volume
Therefore; The number of moles in this solution is 2 L x 2 mol/L = 4 mol
The molecular mass of sucrose is 342.3 g/mol.
Mass = Moles × Molecular weight
Therefore the mass of sucrose in 2 L;
= 4 mol x 342.3 g/mol = 1369.2g
but; 2L/20 = 100 mL
= 1369.2/20 = 68.46
Hence; you would have 68.46 g in 100 mL
Answer:
Ionic bond
Explanation:
When the electronegativity between the two atoms is very large (usually greater than 2.1), this can lead to total transfer of electron from the higher electronegative atom to the lower one.
The total transfer of electrons leads to the formation of ionic bond.
Explanation:
I just looked it up, the answer should be 4.4
Answer:
Yes it is because heating expands molecules of solution which helps to form a solution as it acts as solvent solution.
