Answer:
The molar concentration is 0.114 M (≈0.11 M)
Explanation:
Step 1: Data given
Mass of sucrose = 156 grams
Molar mass of sucrose = 342.3 g/mol
Volume = 4.0 L
Step 2: Calculate moles sucrose
Moles sucrose = mass sucrose / molar mass sucrose
Moles sucrose = 156 grams / 342.3 g/mol
Moles sucrose = 0.456 moles
Step 3: Calculate molar concentration of the solution
Concentration of solution = moles sucrose / volume
Concentration of solution = 0.456 moles / 4.0 L
Concentration of solution = 0.114 M
The molar concentration is 0.114 M (≈0.11 M)
Answer:
The molar concentration of the solution is [tex]0.114 M[/tex]
Explanation:
Molar concentration is the density of the substance per unit volume of particular solute in a solution.
Given:
Mass of sucrose [tex]= 156 g[/tex]
Molar mass of sucrose[tex]= 342.3 g/mol[/tex]
Volume[tex]= 4.0 L[/tex]
Step 1:
To find the moles of sucrose
[tex]= \frac{mass\ of \ sucrose}{molar\ mass\ of\ sucrose}[/tex]
[tex]= \frac{156 g}{342.3g/mol}[/tex]
[tex]= 0.456 moles[/tex]
Step 2:
Calculate the molar concentration of the solution
[tex]=\frac{moles\ of\ sucrose}{volume}[/tex]
[tex]= \frac{0.456moles}{4.0L}[/tex]
[tex]= 0.114 M[/tex]
Therefore, the molar concentration is [tex]0.114 M[/tex]
