## Solved How much of a 14% solution is needed to make 25 ml of

Science Biology Biology questions and answers How much of a 14% solution is needed to make 25 ml of a 6% solution? Record your answer to decimal places. This problem has been solved! You’ll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer.

## How much of a 14% solution is needed to make 25 ml of a 6%

Let x be the volume of the 14% solution needed to make 25 ml of a 6% solution. Using the formula above, we can set up the equation: 0.14x = 0.06 (25) Solving for x, we get: x = (0.06 * 25) / 0.14 x = 10.71 ml Therefore, we need 10.7 ml (rounded to one decimal place) of the 14% solution to make 25 ml of a 6 % solution.

## Dilution Calculator for percent solutions

## Dilution Ratio Calculator

If you have a 1:3 dilution, i.e., a 1:3 dilution ratio, this means that you add 1 unit volume of solute (e.g., concentrate) to 3 unit volumes of the solvent (e.g., water), which will give a total of 4 units of volume. Why is this useful? You may already be using the dilution ratio in your everyday life without knowing it!

## Percent Concentration

(a) If 25 moles of NaCl are present in 100 L of a solution wherein H2O is the solvent, then the concentration of the solution is 25 100 = 0.25mol⋅L−1. (b) What is the molarity of a solution prepared by dissolving 15.0 g of sodium hydroxide in enough water to make a total of 225 mL of solution? Solution.

## Percentage Calculator: Effortlessly Calculate Percentage

We call the first number (2) a numerator and the second number (5) a denominator because this is a fraction. To calculate the percentage, multiply this fraction by 100 and add a percent sign. 100 × numerator / denominator = percentage. In our example, it’s 100 × 2/5 = 100 × 0.4 = 40. Forty percent of the group are girls.
