How many moles of cations are in 1.45 mol of K2SO4?

Answer 1

In the K2SO4 equation, SO4 is not a cation since it consists of negatively charged ions. So K+ is the only cation, and since there are two of them then it is 2 mole K+ per mole K2SO4 .

So 2 x 1.55 = 3.10 mol K+

Answer 2

A cation is the positive ion part of the ionic compound. That means for every mole of potassium sulfate, there are two moles of the cation potassium. So there are 2.90 moles of K+.

Answer 3

There are 2 moles of cations (K+, potassium ion) in one mole K2SO4

So: 2*1.60= 3.20 moles cations

Answer 4

There are 2 moles of K+ cations in 1 mole of K2SO4. Therefore, in 1.45 moles of K2SO4, there would be 2 moles x 1.45 moles = 2.9 moles of K+ cations.

Answer 5

1.90 mol K+ ions

Answer 6

5 moles of potassium

Answer 7

5.25
