## What is the solute of alcohol?

Because water is present in the highest amount, water is the solvent and ethanol is the solute.

## What is the solvent in 70 alcohol solution?

In a solution, solute is present in less quantity and the solvent is present in more quantity. A 70% alcohol solution contains a high amount of alcohol. Thus, the solvent is alcohol.

## What is the percentage by volume if 25 ml of methyl alcohol is added to make 50 ml solution Brainly?

## What is a 20% solution?

Uses of Volume in Daily Life

Unless instructions specify otherwise, you can usually assume that a 20 percent sugar solution means 20g of sugar, a measurement of weight, for every 100 milliliters of water, a measure of volume, especially if you’re mixing the solution for use in biology or physiology.

## What is the volume of a 25% methyl solution that contains 20 mL of metal?

Answer: Because % is per hundred and 4 × 25 = 100 and there is 25% of methyl that is 20mL ,therefore 4 × 20 = 80.

## How do I calculate the concentration of a solution?

Rearranging the equation for concentration allows the mass of solute to be calculated:

1. mass of solute in g = concentration in g/dm 3 × volume in dm 3
2. A solution of sodium chloride has a concentration of 10 g/dm 3. …
3. mass of solute in g = concentration in g/dm 3 × volume in dm 3
4. = 10 g/dm 3 × 2 dm 3

## What is a 10% solution?

A percent solution simply means parts per hundred. For example by weight: A 10% solution by weight simply means that you have 10 grams of compound dissolved in 100 mL of solution. For an example by volume: A 23% solution by volume simply means that you have 23 mL of liquid compound in every 100 mL of solution.
