How many moles are in 2 grams of NaOH?


How many moles are in NaOH?

First, the molar mass of NaOH is 39.997 g/mol. Divide the mass by the molar mass and you’ll have the equation: 60 g / 39.997 g/mol. The grams cancel and you are left with 1.50 moles of NaOH.

How do you convert 2 grams to moles?

To correctly estimate the number of moles, n , of a substance of a specific mass, m , (in grams), you need to follow the grams to moles formula: n = m / M , where, M is the molar mass of this material.

How many moles are in 4 grams of NaOH?

=0.10 (approx.)

How many moles are in 2 grams of he?

Once again, grams cancel out to give moles. So the answer is 2.0 moles of helium. So to recap, to convert moles to grams, we multiplied by the molar mass. To convert grams to moles, we divided by the molar mass.

How many grams are in a mole of NaOH?

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

What is the molar mass of NaOH?

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 grams does NaOH have?

1 mole of sodium hydroxide has a mass of 40.00 g⋅mol−1 .

How many moles are present in 1 gram of sodium hydroxide?

The SI base unit for amount of substance is the mole. 1 grams Sodium Hydroxide is equal to 0.025001806380511 mole.

What is a mole in chemistry?

A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

How do you convert 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).

What is the moles of oxygen?

Moles of a Substance and the Molecular Weight

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g. If we total up the gram amounts of each element in the water molecule = 15.998g/mol + 2(1.008g/mol) we get the molar mass of water = 18.014g/mol.
