Grams and moles are two ways to express mass.Tomasz Sienicki, Creative Commons Many chemical calculations require the number of moles of a material, but how do you measure a mole? One common way is to measure themass in gramsand convert to moles.Converting grams to molesis easy with these ...
Moles are a unit of measurement of chemical compounds. Just like how physical quantities, such as distance, mass, time etc. have measurement units (meters, grams, seconds respectively), similarly, chemicals are measured in moles. In short, you could say that a “mole” is the unit of amoun...
A Mole of Hydrogen Gas The rule is that the mass of a particle in AMU is equal to the mass of a mole of the particles in grams. For example, the atomic mass of a hydrogen molecule (H2) is 2.016 AMU, so a mole of hydrogen gas weighs 2.016 grams. Since there are 1,000 grams in...
No the two are not the same, if you want to convert moles to grams you need to multiply by the molar mass. The relationship is m = n x M where m = mass, n = moles and M = molar mass. Logged Aetos Regular Member Posts: 49 Mole Snacks: +1/-1 Gender: Studying Forensics Re...

Step 2: Find the Mass of the Substance Present From step 1, 1 mmol of potassium = 39.1 mg. Therefore, 50 mmol = (50)(39.098) = 1,955 mg. Step 3: Convert to Parts Per Million As noted above, PPM = mg/L. Since we have 1,955 mg dissolved in 0.5 L, the PPM of potassium in...
Learn how to convert the number of grams of a molecule to the number of moles of the molecule with examples below. This type of conversion problem mainly arises when you are given (or must measure) the mass of a sample in grams and then need to work a ratio or balanced equation problem...
The conversion of joules (j) to moles (mol) commonly is calculated when measuring the energy changes during chemical reactions. A joule is a measure of energy; a mole is a measure of mass. If a chemical reaction produces a certain amount of energy, you can figure out how many moles of...
