What is 6.02 x1023

Avogadro's number is a proportion that relates molar mass on an atomic scale to physical mass on a human scale. Avogadro's number is defined as the number of elementary particles molecules, atoms, compounds, etc. It is equal to 6. Athmane Maurica Professional. How many moles are in a gram? The answer is 0. We assume you are converting between moles In and gram. You can view more details on each measurement unit: molecular weight of In or grams The SI base unit for amount of substance is the mole.

Loana Santasusagna Professional. What is a mole of an element? One mole abbreviated mol is equal to 6. The molar mass of any element can be determined by finding the atomic mass of the element on the periodic table. Josefine Tchalov Explainer. What is Avogadro's constant used for?

One mole of a substance is equal to 6. The number 6. The concept of the mole can be used to convert between mass and number of particles.. Created by Sal Khan. Jilali Lachenschmid Explainer. Who invented the mole? Wilhelm Ostwald. Talia Saumell Explainer. How do I calculate moles? Start with the number of grams of each element, given in the problem. Convert the mass of each element to moles using the molar mass from the periodic table.

Divide each mole value by the smallest number of moles calculated. Round to the nearest whole number. The mole and the Avogadro constant The unit for the amount of a substance is the mole. Molar mass and molecular mass As has been mentioned the molar mass of a substance is the mass of one mole of the substance - 6.

The molecular mass is the mass of one molecule of the substance. The molecular mass is the molar mass divided by the Avogadro constant. Example problems A sample of 2 mg of polonium is found to emit 2. If the relative atomic mass of polonium is , calculate a value for the Avogadro constant. A mole was, therefore, originally defined in terms of mass. On this basis chemists selected a standard number, which is equal to the number of atoms present exactly in 12g of carbon C A mole is the amount of any substance containing as many particles as there are carbon atoms in exactly 12g of the carbon isotope.

It may be noted that while using the term mole it is essential to specify the kind of particles involved. For example, One mole of oxygen atoms contain 6. One mole of oxygen molecules contain 6. Author Information.
