## What is the theoretical %Cu in CuSO4 5H2O?

Determine the concentration by mass percent by dividing the formula weight of CuSO4 by the formula weight of CuSO4-5H2O and multiplying by 100 percent: 159.62 / 249.72 * 100 = 63.92 percent.

## What is the name of the hydrate CuSO4 5H2O?

Copper sulfate pentahydrate

Copper sulfate pentahydrate | CuSO4. 5H2O – PubChem.

## How do you find the theoretical percent of water in a hydrate?

Divide the mass of the water lost by the mass of hydrate and multiply by 100. The theoretical (actual) percent hydration (percent water) can be calculated from the formula of the hydrate by dividing the mass of water in one mole of the hydrate by the molar mass of the hydrate and multiplying by 100.

## What is the percent of Cu in CuSO4?

Anhydrous copper sulfate is 39.81 percent copper and 60.19 percent sulfate by mass, and in its blue, hydrous form, it is 25.47% copper, 38.47% sulfate (12.82% sulfur) and 36.06% water by mass.

## How do you find Percent Composition?

Percent Composition

- Find the molar mass of all the elements in the compound in grams per mole.
- Find the molecular mass of the entire compound.
- Divide the component’s molar mass by the entire molecular mass.
- You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.

## What is the percent composition of water in the hydrate CuSO4 ● 5H2O?

36%

A mole of CuSO4•5H2O contains 5 moles of water (which corresponds to 90 grams of water) as part of its structure. Therefore, the substance CuSO4•5H2O always consists of 90/250 or 36% water by weight.

## What is the molar mass of CuSO4 5H2O?

159.609 g/mol

Copper(II) sulfate/Molar mass

## What is the theoretical percent of water?

The theoretical percentage of water is found by dividing the total mass of water (12 x 18.02 g) by the molar mass of the hydrate (474.46 g). The mass of the hydrate is found by subtraction: 102.636 g – 101.486 g = 1.150 g.

## How do you find theoretical percentage?

To calculate the theoretical percentage of an element in a compound, divide the molar mass of the element by the mass of the compound and multiply by 100. In a chemical reaction, the percent yield of a product is its actual yield divided by its theoretical yield and multiplied by 100.

## What is the percent of copper in CuSO4 5H2O?

Percent composition by element

Element | Symbol | Mass Percent |
---|---|---|

Copper | Cu | 25.450% |

Hydrogen | H | 4.037% |

Oxygen | O | 57.671% |

Sulfur | S | 12.842% |

## What is the percentage of CuSO4?

Commercial copper sulfate is usually about 98% pure copper sulfate, and may contain traces of water. Anhydrous copper sulfate is 39.81 percent copper and 60.19 percent sulfate by mass, and in its blue, hydrous form, it is 25.47% copper, 38.47% sulfate (12.82% sulfur) and 36.06% water by mass.

## What is the percent composition of water?

The percentage of an element in a compound is 100 times the fraction, so for water the mass percent hydrogen is 11.11% and the mass percent oxygen is 88.89%.
