## How do you calculate grams to moles?

Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.

## How many moles of MgCl2 are produced from 1 mole HCI?

We know that 2 moles of HCl produces 1 mol of MgCl2 M g C l 2 .

## How do I calculate moles?

How to find moles?

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

## How do you calculate MgCl2?

For example magensium chloride has the formula unit MgCl2 , i..e., for every magnesium cation there are two chloride anions in the crystal. Or, we would say that the formula weight of MgCl2 = 95.211 g/mol (i.e., 95.211 g of magnesium chloride has a mole of magnesium cations and 2 moles of chloride anions.

## What is the percentage of MgCl2?

The percent composition of Mg in MgCl2 is 25.529% .

## How many protons does MgCl2 have?

Magnesium Chloride (MgCl2) is made up of 1 Magnesium atom and 2 Chlorine atoms. I was unable to find a common name for Magnesium Chloride. Chlorine is a chemical element with the symbol Cl and the atomic number 17. Chlorine has 17 protons and electrons and 18 neutrons.

## 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 do you convert 12g of oxygen gas to moles?

Here we are given the mass of oxygen gas as 12 grams. Molar mass = 2×16 = 32 grams. We know the formula to calculate the number of moles. = 0.375 moles.

## How many grams are in 5 moles?

Therefore, 5 moles × 32.0 g/mol = 160 grams is the mass (m) when there are 5 moles of O2 .

## What is the mass number of MgCl2?

Now, we are given with the compound i.e. magnesium chloride having the chemical formula MgCl2. The atomic mass of magnesium is 24 u, whereas chlorine has the atomic mass 35.5 u. Therefore, the formula unit mass of magnesium chloride is 95 u.

## What is the equivalent weight of MgCl2?

Answer: The Magnesium chloride’s equivalent weight is 47.6 gram.

## How many moles of ions are present in 27.5 g of MgCl2?

Explanation: Moles of magnesium salt = 27.5⋅g95.21⋅g⋅mol−1 = 0.289⋅mol. There are thus 2×0.289⋅mol chloride ions , and 0.289⋅mol magnesium ions , almost an entire mole of ions.
