What is the molar mass of 2NaI?

What is the molar mass of 2NaI?

299.78 g/mol
NaI has a molar mass of 149.89 g/mol , so 2NaI has a molar mass of 149.89⋅2=299.78 g/mol .

How do you find the molar mass of ethanol?

Because 1 mol of ethanol contains 2 mol of carbon atoms (2 × 12.011 g), 6 mol of hydrogen atoms (6 × 1.0079 g), and 1 mol of oxygen atoms (1 × 15.9994 g), its molar mass is 46.069 g/mol.

How can molar mass be calculated?

To calculate the molar mass of a molecule, we first obtain the atomic weights from the individual elements in a periodic table. We then count the number of atoms and multiply it by the individual atomic masses. Lastly, we add all the atomic masses together to get the molar mass.

What is the name of 2nai?

Sodium iodide

What is the molar mass of na2s?

78.0452 g/molSodium sulfide / Molar mass

What is the mass of 2 moles of ethanol?

How do you calculate ethanol?

To find out the concentration of ethanol, we need to know the volume of the fermentation medium. If it was 500 ml (0.5 liters), then the concentration is 0.021 moles/0.5 liters = 0.042 moles/liter (or 42 mM) ethanol.

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).

How do you find moles from molar mass?

To convert between grams and moles, you would use the substance’s molar mass. To go from grams to moles, divide the grams by the molar mass. 600 g58.443 g/mol = 10.27 mol of NaCl.
