Question

5.98 g of K Al (SO₄)₂ is equivalent to how many moles?

Answer 1

0.023 moles s equivalent to 5.98 g of K Al (SO₄)₂.

Step-by-step explanation:

Data given:

mass of K Al (SO₄)₂ = 5.98 grams

atomic mass of 1 mole K Al (SO₄)₂ =258.25 grams/mole

39 + 27+ (96.0 x3)= 258.25 grams (K=39 grams/mole, Al = 27 grams/mole, SO4 is 96 grams/mole)

To determine the number of moles the formula used is:

number of moles =
`(mass)/(atomic mass of 1 mole)`

when the values are put in the equation we get the Number of moles the compound has in it in the given mass of that compound.

So,

number of mole=
`(5.98)/(258.25)`

= 0.023 moles

Thus we see that 5.98 grams of K Al (SO₄)₂ is equal to 0.023 moles of it.
