## What is a 50% solution?

Depends if you see v/v (volume/volume) or w/v (weight/volume) %.

50% (w/v) NaCl would be 50 grams in 100 mL of water.

…

50% (w/v) NaCl would be 50 grams in 100 mL of water.

I always interpreted that to be 50 grams of NaCl in 100 mL of solution (solution = water + salt)..

## What does V V mean?

Concentration: Volume/Volume % When the solute is a liquid sometimes it is convenient to express its concentration in volume/volume percent (v/v %). The definition of v/v % is. Wine has about 12 mL of alcohol (ethanol) per 100 mL of solution.

## How do you make a 10% solution of NaCl?

We can make 10 percent solution by volume or by mass. A 10% of NaCl solution by mass has ten grams of sodium chloride dissolved in 100 ml of solution. Weigh 10g of sodium chloride. Pour it into a graduated cylinder or volumetric flask containing about 80ml of water.

## How do you make a .5 solution?

Dilute the compound with the necessary amount of solvents. For example: Mix 500 mL of water and 25 g of NaCl to make a 5% solution. Remember, if you’re diluting a liquid compound, you must subtract out the volume of liquid being added from the final volume: 500 mL – 25 mL = 475 mL of water.

## What is a 2% solution?

2% w / w solution means grams of solute is dissolved in 100 grams of solution. Weight / volume % 4% w / v solution means 4 grams of solute is dissolved in 100 ml of solution. Volume / weight % 3% v/ w solution means 3 ml of solute is dissolved in 100 grams of solution.

## What is a 10% solution?

A 10% of NaCl solution by mass has ten grams of sodium chloride dissolved in 100 ml of solution. Weigh 10g of sodium chloride. Pour it into a graduated cylinder or volumetric flask containing about 80ml of water. … A 10% of alcohol solution by volume has ten ml of alcohol dissolved in 100ml of solution.

## How do you calculate dilution?

Example 2: Suppose you must prepare 400 ml of a disinfectant that requires 1:8 dilution from a concentrated stock solution with water. Divide the volume needed by the dilution factor (400 ml / 8 = 50 ml) to determine the unit volume. The dilution is then done as 50 ml concentrated disinfectant + 350 ml water.

## What does 5% w/v mean?

The solution’s mass by volume percent concentration, m/v % , tells you the number of grams of solute present for every 100 mL of the solution. In your case, the solution is said to have a mass by volume percent concentration of 0.5% , which means that you get 0.5 g of solute for every 100 mL of the solution.

## How do you calculate solutions?

The standard formula is C = m/V, where C is the concentration, m is the mass of the solute dissolved, and V is the total volume of the solution. If you have a small concentration, find the answer in parts per million (ppm) to make it easier to follow.

## How do you make a 50 solution?

50% NaOH means 50 g NaoH dissolved in water and the Solution made up to 100 ml. So 500 g of NaOH in 1 Liter of Solution is 50% Solution. NaOH is highly soluble in water. 1110 g of NaOH dissolves in 1 liter of Solution,at 25°C.

## How do you make a 10% solution?

We can make 10 percent solution by volume or by mass. A 10% of NaCl solution by mass has ten grams of sodium chloride dissolved in 100 ml of solution. Weigh 10g of sodium chloride. Pour it into a graduated cylinder or volumetric flask containing about 80ml of water.

## How do you make a 0.1% solution?

So the equivalent weight of NaOH is 40. To make 1 N solution, dissolve 40.00 g of sodium hydroxide in water to make volume 1 liter. For a 0.1 N solution (used for wine analysis) 4.00 g of NaOH per liter is needed.

## What is a 5% solution?

Volume / volume % www.citycollegiate.com. 5% v / v solution means 5 ml of solute is dissolved 100 ml of solution.

## How do you make a 1% solution?

The mass of a solute that is needed in order to make a 1% solution is 1% of the mass of pure water of the desired final volume. Examples of 100% solutions are 1000 grams in 1000 milliliters or 1 gram in 1 milliliter.

## What is a 1% solution?

A one percent solution is defined as 1 gram of solute per 100 milliliters final volume. For example, 1 gram of sodium chloride, brought to a final volume of 100 ml with distilled water, is a 1% NaCl solution. To help recall the definition of a 1% solution, remember that one gram is the mass of one milliliter of water.
