Question

There are 1.2 x 1024 formula units
CaCl2 in a sample. How many grams of
CaCl2 is this? The molar mass of
CaCl2 is about 111 g/mol.

Answer 1

mol CaCl₂ = 1.2 x 10²⁴ : 6.02 x 10²³ = 1.993

mass = 1.993 x 111 g/mol = 221.223 g

Answer 2

It is 221.223 grams of CaCl2.

mol CaCl₂ = 1.2 x 10²⁴

6.02 x 10²³ = 1.993

mass = 1.993 x 111 g/mol

= 221.223 g.

How many grams of CaCl2 are in a mole?

Suppose that for a sure test you need 3.00 moles of calcium chloride (CaCl2). on the grounds that calcium chloride is stable, it'd be convenient to use a balance to measure the mass that is wished. The molar mass of CaCl2 is 110.98 g/mol.

So if 1 mole of calcium chloride carries 6.022⋅10^23 components gadgets and has a mass of one hundred ten. ninety-eight grams, you can say that 6.022⋅1023 system gadgets of calcium chloride have a mass of 110.98 g .
