A great way to remember nuclear chemistry is looking at the numbers and seeing what adds up. From there, you can see if the bottom number is different and look the element up on the periodic table.

Consider 55 mL of water (H2O) in a beaker and 55 mL of acetone <(CH3)2CO> in an identical beaker under identical conditions. Com

Weaker

Explanation:

The vapor pressure of a solution describes how quickly a solution will turn into vapour. If we say that a solution has a high vapour pressure, we are actually saying that the solution turns into vapour more quickly.

Acetone has a higher vapour pressure than water so acetone turns to vapour quicker than water.

Vapour pressure has a lot to do with the magnitude of intermolecular forces in solution. The stronger the magnitude of intermolecular forces, the lower the vapor pressure and the more slowly the solution evapourates.

So, the hydrogen bonds in water provides stronger intermolecular forces than dispersion and dipole interaction in acetone. Hence, water vaporizes more slowly than acetone.

Calculate the mass of NaCl needed to make 40% solution from 3kg of water ? Could you explain step by step please :-)

Ok so 40 percent of 3000 grams which is 3 kg is 1200 grams So you would need 1.2kg or 1200 grams to make a 40% solution
