Mercury is 13.6 times as dense as liquid water. What would be the reading of a water-filled barometer at normal atmospheric pres

Density = mass / volume
Because the dimensions of the barometer are the same for each case, we can compare the heights of the liquids instead of the volume.

ρ(mercury) = 13.6ρ(water)
mass(mercury)/760 = 13.6 x mass(water)/Height(water)

Masses of the liquids will also be the same.

Height of water = 13.6 x 760
Height of water = 10,336 mm

You have a cup of water and a packet of powdered juice mix. You add some of the juice mix to the cup of water and stir. The powd
dusya [7]

The correct answer is "The solution is immiscible".

A solution is said to be immisicible when two or more substance do not mix in each other to form a homogeneous solution.

However, a misicible solution is one where two or more substances mix in each other to form a homogeneous solution.

In an unsaturated solution more solute can still dissolve in the solvent to form a solution. However, in this case more powdered juice mix does not dissolve in the water.
