An engine has a 5.4 litre capacity cooling system. If the most ideal solution of antifreeze for this engine is a 59.6 % solution (a mix of 59.6 An engine has a 5.4 litre capacity cooling system. If the most ideal solution of antifreeze for this engine is a 59.6 % solution (a mix of 59.6 % pure antifreeze and 40.4 % water). How much pure antifreeze (in litres) must be combined with a 35.4 % solution to achieve 5.4 litres of t% pure antifreeze and 40.4 % water). How much pure antifreeze (in litres) must be combined with a 35.4 % solution to achieve 5.4 litres of the ideal solution?
