How many moles are in 39.10 g of potassium?
The molar mass of potassium is 39.10 g/mol. Therefore: n moles of potassium atoms will have a mass of (n TIMES 39.10) g. OR: 6.89 moles of potassium atoms will have a mass of (6.89 TIMES 39.10) g, which is equal to 269 g.
How many moles are found in 25 grams of potassium?
25122.4 = moles. 2.05 moles of Potassium Chlorate. There is a 1:1 mole ratio. 1 mole of Potassium Chlorate will produce 1 mole of Potassium Chloride.
What is 1 mole in grams?
The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

What is the mass of 2.5 mole of co2?
2.5 mole of co2 = 2.5 x 4.4 = 11g.
How many moles are in 5 grams?
How many moles are 5 grams of calcium ? (Atomic mass of calcium =40u). 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.
What name is given to the number of particles in a mole?
Avogadro’s number is the number of units in one mole of a substance, or 6.02214076 × 1023. This number is also called the Avogadro constant.
