Add water 4 of 8 What does GDA stand for? Guideline Daily Amount, this informs you how much nutrient a person needs each day for a healthy diet 5 of 8 What is the formula used to find the concentration in g/dm3? Concentration=Mass of solute (g) / Volume of solvent(dm3) 6 of 8 What is the formula used to find the concentration in mol/dm3? Concentration=Amount of solute (mol) / Volume of soslvent (dm3) 7 of 8 Convert 1200cm3 into dm3... 1.2dm3 8 of 8
