Question

How many moles of Na+ are present in 250 mL of 0.05
M Na2SO4 solution?

Answer 1

$\huge\underline\bold\red{AnsWer}$

1.2 × 10^24ions are there

.......not confirm pl check once also

explanation:-

we usually talk about a solution so, let me rephrase your question. how many moons of Na+ and Cl+ are present in a solution in which 1 mole ofNaCl is completely dissolved in water?

first, NaCl is very soluble in water

solid NaCl. dissociate completely into ions of Na+ And Cl- when forming an aqueous of solution . this is written:

1NaCl (s) ➡️1 Na (aa) + 1Cl - (aq)

there are two moles of ions (one solid and one chloride)on the product side. A mole is Avagadro's number.

2moles × 6.02. × 10^23 ions / moles = 1.2 × 10^24 ions answer
