How do you convert 12 grams of oxygen to moles?

Therefore, 12 g of oxygen gas has 0.375 moles.

What is the number of moles in a 12.0 g sample of oxygen gas O2?

= 12 X 1 / 32 = 0.375 mole.

How many moles are in 12 grams?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023). Calculate the number of atoms in 2.45 mol of copper.

How many moles are in 8g of O2?

8 g of oxygen is composed of 0.5 moles.

How many grams are in 4 moles of oxygen?

Since 1 mole of oxygen is equivalent to 32 g, 4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = 128 g. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.

How many moles are in 5 grams?

Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. Thus, there are 0.125 mole in 5 grams of calcium. Thus, 5 grams calcium constitute 0.125 mole of calcium. In the above case, mass of element is 5 grams and molar mass of element is 40g/mol.

How is mol calculated?

  1. First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
  2. For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
