A solution is prepared by adding 25.0 g of methanol to water to make a total volume of solution of 95.4 mL. What is the weight/volume percent of this solution?

26%

Explanation:

Given data:

Mass of solute = 25.0 g

Volume of solution = 95.4 mL

Weight/volume % solution = ?

Solution:

The w/v% of any solution is calculated by dividing the mass of solute into total volume of solution multiply by 100.

Formula:

w/v% = weight of solute / volume of solution × 100

Now we will put the values in formula:

w/v% = 25.0 g /  95.4 mL × 100

w/v% = 0.26× 100

w/v% = 26%

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
