A 0.200M solution of sodium carbonate Na2CO3 is made by dissolving 5.30g of the solid in water and making up the mark in a standard flask What volume must the flask be?
To find the volume of the flask, first calculate the moles of Na2CO3 using its molar mass. Then use the molarity and moles to find the volume using the formula Molarity (M) = moles/volume (in liters). The volume of the flask needed is then the inverse of the molarity.
