## How many moles of acetic acid are produced?

Conversions Mass – Mole – Numbers

How many moles of acetic acid? | = 25 g x (1 mol acetic acid/60 g) = 0.417 mol |
---|---|

How many moles of oxygen? | = 2×0.417 mol = 0.834 mol of O |

How many total moles of atoms? | = 8×0.417 mol = 3.34 mol of atoms |

How many carbon atoms? | = 0.834 mol x(6.022×10^+23/mol) = 5.02×10^+23 C atoms |

## How do you calculate moles of acetic acid?

Going back to moles, you can calculate the mass of acetic acid in the solution by multiplying the moles by the molar mass of the acetic acid ( 60.05gmol ). This will then be divided by the volume of the solution in mL.

## What is the mass of 1 mole of carbon?

Exactly 12 grams of pure carbon-12 powder is known as one mole. The number of atoms of carbon-12 present in this one mole sample is 6.022 136 7 x 1023. This number is known as Avogadro’s number.

## How do I calculate moles?

- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.

## Why is mole concept important?

Explanation: THE mole is important because it allows chemist to work with a subatomic world with macro world units and amount. Atoms molecules and formula units are very small and very difficult to work with usually. However the mole allows a chemist to work with amount large enough to use.

## How many moles is NaOH?

The molar mass of the compound NaOH is 40 g/mol.

## How do you convert from moles to grams?

You have three steps to convert mole values to grams.

- Calculate how many moles are mentioned in the question.
- Find the molar mass of the substance.
- Multiply both the values.
