## What is the mole formula?

Avogadro’s number is a very important relationship to remember: **1 mole = 6.022×1023 6.022 × 10 23 atoms**, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

## How much is a mole of copper sulfate?

So copper (II) sulfate pentahydrate has a molar mass of: (63.546 x 1) + (32.066 x 1) + (15.9994 x 4) + (1.0079 x 10) + (15.9994 x 5) = **249.6856 g/mol**.

## How do you find the moles of copper sulfate?

If you want to prepare 1L of a 0.2 M solution, for example, plug those values into the formula to solve for moles this way: M = mol/L and 0.2 M = x mol/1L. Calculate the number of moles of copper (II) sulfate pentahydrate needed. This operation requires a simple cross-multiplication: **x = (0.2 M) (1L) = 0.2 mol**.

## What is mole physics?

The mole is **the SI unit for the amount of a substance** and one of the seven fundamental SI units. It is defined as the amount of substance of a system that contains as many elementary entities as there are atoms in 0.012 kilograms of carbon-12 (BIPM 1998, p.

## How do you find moles in physics?

**The unit is denoted by mol.**

- The formula for the number of moles formula is expressed as.
- Given.
- Number of moles formula is.
- Number of moles = Mass of substance / Mass of one mole.
- Number of moles = 95 / 86.94.

## How many atoms are in CuSO4?

**21 atoms** are present in compound cuso4.

## How do you find the concentration of CuSO4?

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. This means that a 100-gram sample of copper sulfate pentahydrate will contain 63.92 grams of copper sulfate.

## What is the equivalent weight of CuSO4?

For ionic salts we take the amount of charge present on an ion (cation or anion) to be the n factor, we have equivalent mass of CuSO4 as 159.609/2 = **79.804 gm/mol**.
