Calculating Molarity of Solution Containing Glucose
Step 1: Calculate the number of moles of glucose
To calculate the number of moles of glucose, we need to use the formula:
moles = mass/molar mass
Mass of glucose = 3 g
Molar mass of glucose = 180 g/mol
moles = 3/180
moles = 0.01667 mol
Step 2: Calculate the volume of the solution in liters
To calculate the volume of the solution, we need to use the formula:
Volume = Mass/Density
Mass of water = 30 g
Density of water = 1 g/mL
Volume = 30/1
Volume = 30 mL
As we need the volume in liters, we will convert 30 mL to liters by dividing it by 1000:
Volume = 30/1000
Volume = 0.03 L
Step 3: Calculate the molarity of the solution
The formula to calculate molarity is:
Molarity = moles/volume
moles = 0.01667 mol
Volume = 0.03 L
Molarity = 0.01667/0.03
Molarity = 0.5556 M
Therefore, the molarity of the solution containing 3g glucose dissolved in 30 g of water is 0.5556 M.
