What is the mass of 5 mole molecules of nitrogen?
[molecular mass of nitrogen is 28g]
What is the mass of 5.00 moles of C?
Carbon-12 refers to the isotope of carbon that has an atomic mass of 12.0000 g. Thus, the mass of one mole of carbon-12 is 12.0000 g. Therefore, the mass of 5 moles of C-12 is 5 × 12.0000 = 60.0000 g. The mass of 5 moles of C-12 is 60.0000 g.
What is the mass in grams of 5 moles of?
= 320 grams. Therefore, the mass of 5 moles of So2 is approximately equal to 320 grams.

What is the formula for moles to grams?
Moles to grams example problem
Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.
What is the mass of 0.2 mole of nitrogen gas?
Therefore, 0.2 moles of atoms of nitrogen consists of =1.205×1023 atoms. Therefore, 3.2g of sulphur contains 0.6023×1023 atoms of sulphur.
How do u calculate mass?
Mass is always constant for a body. One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass. The SI unit of mass is “kilogram”.
What is the mole formula?
Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).
