Hurry ! calculating - a sample it barium nitrate is placed into a jar containing water. the mass of the barium nitrate sample is 27g. assume the water is at 20°c and that the resulting barium nitrate solution is saturated. what mass of water is present in the jar?

Answer : The mass of of water present in the jar is, 298.79 g

Solution : Given,

Mass of barium nitrate = 27 g

The solubility of barium nitrate at is 9.02 gram per 100 ml of water.

As, 9.02 gram of barium nitrate present in 100 ml of water

So, 27 gram of barium nitrate present in of water

The volume of water is 299.33 ml.

As we know that the density of water at is 0.9982 g/ml

Now we have to calculate the mass of water.

Therefore, the mass of of water present in the jar is, 298.79 g

you should just be yourself and not let any body tell you other wise.

explanation:

why?

because if they don't love you for your self then they don't deserve you.
