8 moles of KCl are needed.

3 x 0.2 = 0.6 moles
You have 4.8 moles and this is in 1.6 litres. 4.8 moles / 1.6 is 3 moles. This is also now 3 molar.
All of the moles of pure acid will have dissolved in the flask.
The number of moles is 0,527.
In moles of a substance dissolved in 1 L of water.
In moles of a substance dissolved in 1 L of water.
8 moles
4.00 moles/2.00 L = 2.00 moles/L = 2.00 M
first determine the number ofmoles dissolved in given solution then .5 moles moles dissolved in 800g. as comparison with 1000g of water, we know 100g of water dissolve only.1 moles of a glucose so we .7moles of glucose dissolve in 800g.
8 moles of KCl are needed.

Well the definition of molarity is how many moles in every litre. You already have your answer expressed as moles in a litre, approximately. Density is approximately 1000g per litre, therefore it will be approximately 2 molar. (You haven't expressed temperature, but density should remain close to 1).
3 x 0.2 = 0.6 moles
