----If 5.25 liter of antifreeze solution (specific gravity = 0.820) is added to 4.20 liter of water to make a 9.45 liter mixture, what is the specific gravity of the mixture?-----(adsbygoogle = window.adsbygoogle || []).push({});

I know that Specific gravity = density of substance/ density of water. The specific gravities of the antifreeze solution and the water are known...but I have no idea how to find the specific gravity of the mixture. Do I multiply the specific gravity by how many liters of the substance there is and then add the together? Thanks for any help.
