# Molarity to Weight Percent Calculator

## Molarity to Weight Percent Calculator

Enter any 3 values to calculate the missing variable

Do you want to convert molarity to weight percent? Enter molarity, total volume of substance, molar weight, the mass of entire solution and weight percent into the calculator to find the weight of molarity.

### What Is Molarity to Weight Percent?

Molarity (M) measures the concentration of a solution in moles of solute per liter of solution. Weight percent (wt%) expresses the concentration as the mass of solute divided by the total mass of the solution, multiplied by 100.

### How to Use the Calculator

To use the calculator, follow these steps:

**Enter Molarity (mol/mL)**: Input the molarity into the calculator to find the weight percent.**Enter Total Volume of Substance (mL)**: Provide the total volume of the substance to calculate the weight percent.**Enter Molar Weight (g/mol)**: Input the molar weight of the solute.**Enter Total Mass of the Entire Solution (g)**: Enter the total mass of the solution to find the missing value.**Enter Weight Percent (%)**: Input the weight percent if you have it to find other missing values.

**Example Values**

For example:

**Molarity**: 0.05 mol/mL**Total Volume**: 1000 mL**Molar Weight**: 180 g/mol**Total Mass**: 50000 g**Weight Percent**: 0.18 %

### Formula

The formula to convert molarity to weight percent is:

`$\text{WeightPercent}=\left(\frac{\text{Molarity}\times \text{Volume}\times \text{MolarWeight}}{\text{TotalMass}}\right)\times 100$`

**Variables**

Variable | Description |
---|---|

Molarity (M) | Molarity in mol/mL |

Volume (V) | Total volume in mL |

Molar Weight | Molar weight in g/mol |

Total Mass | Total mass of the solution in g |

Weight Percent | Weight percent (%) |

## Calculation Examples

### Example 1

**Molarity**: 0.1 mol/mL**Volume**: 500 mL**Molar Weight**: 100 g/mol**Total Mass**: 55000 g

**Calculation:**

**Calculate Weight Percent**:

`$$\text{WeightPercent}=\left(\frac{0.1\times 500\times 100}{55000}\right)\times 100=0.0909\mathrm{\%}$$`

### Example 2

**Molarity**: 0.2 mol/mL**Volume**: 250 mL**Molar Weight**: 150 g/mol**Total Mass**: 40000 g

**Calculation:**

**Calculate Weight Percent**:`$$\text{WeightPercent}=\left(\frac{0.2\times 250\times 150}{40000}\right)\times 100=0.1875\mathrm{\%}$$`
