## How many moles are in CoCl2?

The molar mass of CoCl2 is 129.83 g/mol The molar mass of H2O is 18.02 g/mol and the molar mass of 6H2O is (6)( 18.02 g/mol) = 108.12 g/mol The molar mass of CoCl2∙6H2O is 237.95 g/mol (The 6 in front of the H2O needs to be taken into account!)

## What is the mass of 1 mole of CoCl2?

Number of moles=100g/ 18.02 g/ moles= 5.55 moles.

## How do you convert from grams to moles?

Divide the number of grams of the compound, NaOH, by the molecular weight and as a result, the grams (g) unit cancels and all we have left is the unit mol (moles).

## How do I calculate moles?

How to find moles?

- Measure the weight of your substance.
- Use a periodic table to find its atomic or molecular mass.
- Divide the weight by the atomic or molecular mass.
- Check your results with Omni Calculator.

## How many particles are there in cocl2?

In hydrated cobalt(II) chloride, there exist six water molecules per molecule of cobalt(II) chloride. So, in 3 moles of the substance, there’ll be 3⋅6=18 moles of water molecules. Remember that a mole of molecules contains 6.02⋅1023 molecules.

## How many grams are there in 2.3 moles of silver?

Use dimensional analysis to convert the number of atoms to moles. Convert the moles of Ag to mass. The mass of 2.3 × 10²⁴ Ag atoms is approximately 410 g.

## What is 1g mole?

(Often called gram-molecular weight.) A mass of a substance in grams numerically equal to its molecular weight. Example: A gram-mole of salt (NaCl) is 58.44 grams. Terms G. …

## How many grams are in moles?

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

## Why do we convert moles to grams?

When substances react, they do so in simple ratios of moles. However, balances give readings in grams. Balances DO NOT give readings in moles. So the problem is that, when we compare amounts of one substance to another using moles, we must convert from grams, since this is the information we get from balances.

## How do you calculate MOL from molarity?

To calculate the number of moles in a solution given the molarity, we multiply the molarity by total volume of the solution in liters.
