What measures are used to calculate the percent by volume of a solution?

s the solution expressed in the unit %. ... Solvent is a liquid which dissolves the solute.

Explanation:

Volume/volume percentage (v/v percent) is a measure of the concentration of a substance in a solution. It is expressed as the ratio of the volume of the solute to the total volume of the solution multiplied by 100. Examples: Wine has a typical alcohol content (v/v percent) of 12 percent.

See the answer below, please.

Explanation:

The volume / volume percentage relates the volume of solute / solution volume and this is multiplied by 100.

In the case of weight / volume percentage, relate grams of solutes to milliliters of solution, then this is multiplied by 100.

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
