How do I convert from moles to grams?

The process of converting from moles to grams is a fundamental concept in chemistry and can be easily remembered using the mnemonic "We Mole-tiply by the Molar Mass of a compound."

Here's a step-by-step description of how to perform this conversion:

Determine the Number of Moles: Start with the given amount of a substance in moles.

Find the Molar Mass: Look up the molar mass of the compound in a periodic table or a reliable source. The molar mass is usually expressed in grams per mole (g/mol).

Multiply Moles by Molar Mass: Multiply the number of moles from step 1 by the molar mass of the compound from step 3. The units in this step will cancel out moles, leaving you with the answer in grams.

Grams = Moles × Molar Mass

Example::

Example: Convert 2.00 moles of water (H₂O) to grams.

You already have the number of moles, which is 2.00 moles of H₂O.

The molar mass of water (H₂O) is approximately 18.02 g/mol.

Multiply the number of moles (2 moles) by the molar mass (18.02 g/mol):

Grams = 2.00 moles × 18.02 g/mol = 36.03 grams

So, 2.00 moles of water is equivalent to 36.03 grams of water.

This conversion method ensures that you correctly find the mass in grams corresponding to a given number of moles for a specific compound.

I am a retired Ph.D. organic chemist, but I thoroughly enjoy your short chemistry videos. I frequently learn something new. In all my years of studying chemistry I had never heard anyone use the term "mole-tiply." This is a great mnemonic device for new general chemistry students. I love your channel.

even though you dont get much views, just know you are helping 400 students get a better grade in their sciences, keep it up bro these vids help me so much.

Sir can you make a video on s-block elements, p-block elements and d and f-block elements?

Prof can you clear this up? 1st: Does the sulphate ion form coordinate bonds attached to two of its oxygens? (Here presuming a max of 2 coordinate bonds and 2 single bonds one with each oxygen).
If it does, then what is the distinction between the sulphate ion having coordinate bonds (along with single bonds )and the set of resonating structures of it which has 2 double and 2 single bonds, alternating through the molecule. And lastly, are all single bonds attached to oxygen" coordinate covalent", asking cuz most books don't show tail of the vector(representing donar atom involved in coordinate bonding) and its arrowhead (representing the receiver atom involvedin the same) .This also leads to a cunfusion of people presuming a difference between the single bond being distinct from the coordinate covalent bond when the bond order of oxygen is 1. So to sum the last statement up, are all single bonds attached to oxygen coordinate covalent because of which it has 3 lone pairs and a negative charge?

Hello Sir, I have watch your videos and found them very helpful for my self. I have a doubt about why hrodnium(H3O+) is more acidic that ammonium (NH4+)? can you make video on it

Interesting trick to memorize the convertion. Nevertheless, I consider the key of any types of convertion is knowing how to cancel the original unit and convert it to new unit.

This is simply changing the formula of # moles (n=m/M) into (n*M=m)
