40 g of gasoline are mixed with 45 g of water. What is the average density of the mixture?

• Physics -

The following are densities in kg/m^3: ethyl alcohol, 790; gasoline, 680; sea water, 1030; mercury, 13600.

• Physics -

Is the water that gets mixed sea water? You didn't say.

• Physics -

it is fresh water

• Physics -

Fresh water's density is 1000 kg/m^3.

The average density of the mixture is
40*680 + 45*1000/95
