Dilutions Worksheet - Solutions If 45 mL of water are added to 250 mL of a 0.75 M K2SO4 solution, what will the
molarity of the diluted solution be?
(0.75 M)(250 ml) = M2 (295 mL)
M2 = (0.75 M) (250 mL) = 0.64 M
Where did the 295ml came from ????
The original solution was diluted from 250 mL to 295 mL
We can use the dilution formula to calculate the concentration of the diluted solution.
The amount of material in a particular volume of the solution is measured in molarity that describes as the mole number of solute in 1 liter of solution that is referred to as molarity.
Its original solutions were reduced in volume from 250 mL to 295 mL. You could use the dilution method to calculate the quantity of the solution.
Apply value into the formula:
Therefore, the final answer is "0.64 mol/L".
Name at least 4 other gases in the atmosphere besides oxygen and nitrogen

Why do comets have tails
Comets are composed of ice, dust and frozen gases. The core of the comet is known as nucleus which is formed of rocks and frozen gases. Coma is the atmosphere of the comet. As the comet enters the inner solar system, the coma expands due to sublimation of frozen gases. As it nears the sun, the coma extends backwards and forms a long tail. It extends backwards due to the solar wind. The charged particles from the sun take away the evaporated material and dust of the comet backwards forming tail.
As a comet approaches the Sun, it starts to heat up. The ice transforms directly from a solid to a vapor, releasing the dust particles embedded inside. Sunlight and the stream of charged particles flowing from the Sun – the solar wind – sweeps the evaporated material and dust back in a long tail.
