60 Ml of 0.10m of K2s2o8 Calculate Mass

Reviewed by Calculator Editorial Team

Potassium persulfate (K2S2O8) is a common oxidizing agent used in various chemical processes. Calculating the mass of a solution involves understanding the molar concentration and volume. This guide explains how to determine the mass of 60 ml of a 0.10 M K2S2O8 solution.

Introduction

Potassium persulfate (K2S2O8) is a white crystalline compound that dissociates in water to form K+ and S2O82- ions. The molar mass of K2S2O8 is 222.28 g/mol.

When preparing a solution, the mass can be calculated from the concentration and volume. The formula for mass calculation is:

mass (g) = concentration (M) × volume (L) × molar mass (g/mol)

This formula allows you to determine the mass of solute in a given volume of solution.

Calculation Method

To calculate the mass of 60 ml of 0.10 M K2S2O8 solution:

  1. Convert the volume from milliliters to liters: 60 ml = 0.060 L
  2. Multiply the concentration (0.10 M) by the volume (0.060 L) to get moles of solute
  3. Multiply the moles by the molar mass (222.28 g/mol) to get grams of solute

Note: The calculation assumes the solution is dilute enough that the density is approximately equal to water (1 g/ml).

Worked Example

Let's calculate the mass of 60 ml of 0.10 M K2S2O8:

  1. Volume = 60 ml = 0.060 L
  2. Moles of K2S2O8 = 0.10 M × 0.060 L = 0.0060 moles
  3. Mass = 0.0060 moles × 222.28 g/mol = 1.3337 g

The mass of K2S2O8 in the solution is approximately 1.33 g.

Applications

Potassium persulfate is used in various industries:

  • Textile industry for bleaching and dyeing processes
  • Water treatment for oxidation of organic contaminants
  • Laboratory chemistry for oxidation reactions
  • Food industry as a preservative and bleaching agent

Understanding the mass calculation helps in proper solution preparation and cost estimation.

FAQ

What is the molar mass of K2S2O8?

The molar mass of potassium persulfate is 222.28 g/mol, calculated as 2×39.10 (K) + 2×32.07 (S) + 8×16.00 (O).

How do I convert milliliters to liters?

Divide the volume in milliliters by 1000 to get liters. For example, 60 ml = 0.060 L.

What if the solution is not dilute?

For concentrated solutions, you should account for the actual density of the solution rather than assuming it's equal to water.

Can I use this calculation for other persulfates?

Yes, the same formula applies to other persulfates, but you must use the correct molar mass for each compound.
