Question

how many moles is 130g of cocl2

Answer 1

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

Answer 2

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

How to calculate number of moles?

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).
