Calculate the concentration of 5g dextrose in molarity

Molarity of dextrose = 0.03 mol / L

Explanation:

Given data

mass of dextrose = 5 g

Concentration (Molarity) = ?

Solution

as mass is given so we find out number of moles

Moles = mass / molar mass

Molar mass of dextrose = 180.156 g/mol

Moles = 5 g / 180.156 g/mol

Moles = 0.03 moles

Now we find out molarity

Molarity = moles of solute / Litres of solution

As volume is not given so we suppose it as 1 L

Molarity of dextrose = 0.03 mol / 1 L

Molarity of dextrose = 0.03 mol / L

your answer is c) plasma
