how many moles is 130g of cocl2

Answer:

1.3142 mol CoCl2

Explanation:

Well, to answer this we need to find out how many grams are in a single mole of CoCl2. Two find that we need to get the molar mass of CoCl2

Co = 28.0101 g Co per mole

Cl = 35.453 * g Cl per mole

28.0101 + 2 * 35.453 = 98.9161 g CoCl2 per mole

Now, we divide:

130/98.9161 = 1.3142 mol CoCl2

There are 1.31 moles in 130grams of cobalt chloride (CoCl2). Details about how to convert mass to moles can be found below.

The number of moles of a substance can be calculated by dividing the mass of the substance by its molar mass.

According to this question, there are 130g of CoCl2.

molar mass of CoCl2 = 28 + 35.5(2) = 99g/mol

moles = 130g ÷ 99g/mol

moles = 1.31 moles

Therefore, there are 1.31 moles in 130grams of cobalt chloride (CoCl2).
