Best answer: How many grams of CaCl2 are in 48 moles?

How do you find moles of CaCl2?

Calculation: If 1 mole CaCl2 = 6.02 x 1023 CaCl2 formula units, How many Cl– ions are in 1 mole of CaCl2? 1 mole of CaCl2 consists of 1 mole Ca2+ and 2 mole Cl–. If 1 mole of Cl– is 6.02 x 1023 Cl– ions, then 1 mole of CaCl2 contains (2 x 6.02 x 1023) Cl– ions or 1.20 x 1024 Cl– ions.

How many grams of CaCl2 are in 3 moles of it?

And thus 3 mol of CaCl2 have a mass of 3⋅mol ×110.98⋅g⋅mol−1 ≅ 333⋅g .

How many moles are in 48 grams?

Or to be specific, how many moles of carbon are there in 48 grams of carbon? The answer is 4 moles

How many moles of CaCl2 are in 1.5 g of CaCl2 2h2o?

Calculate how many moles of CaCl2•2H2O are present in 1.50 g of CaCl2•2H2O and then calculate how many moles of pure CaCl2 are present in the 1.50 g of CaCl2•2H2O. Record the answers in Data Table 1.

Initial: CaCl2 x 2H20 (g) 1.50 g
Actual: CaCO3 (g) 1.4 g

How many grams of CaCl2 are in 250 ml of 2.0 M CaCl2?

The solution contains 0.50 mol or 55 g of CaCl2 . You know there are 2.0 mol of CaCl2 in 1 L of solution. (40.08 + 2 × 35.45) g=(40.08 + 70.90) g=110.98 g .

How many grams are in a mol?

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.

How do I calculate moles?

How to find moles?

  1. Measure the weight of your substance.
