Moles of glucose = 14.7/180.15 = 0.0816moles.
Mass of solvent(water) = density of water x volume = 1 x 150 g = 150g
Mass of water in Kg = 0.15 Kg
Molality of glucose = moles of glucose/ mass of water
= 0.0816 / 0.15 = 0.54 molality.
<h3>
Answer:</h3>
0.002 moles
<h3>
Explanation:</h3>
Concept tested: Molarity
We are given;
- Volume of HCl as 20 ml or 0.02 L
- Molarity of HCl solution as 0.10 M
We are required to calculate the number of moles of HCl
What is molarity?
- Molarity is the concentration of a solution in moles per liter
How is it calculated?
- It calculated by dividing number of moles by volume;
- Molarity = Number of moles ÷ Volume
To calculate the number of moles we rearrange the formula;
Moles = Molarity × Volume
In this case;
Moles of HCl = 0.10 M × 0.02 L
= 0.002 moles
Therefore, the number of moles of HCl is 0.002 moles
