Question

How many ions are there in 0.187 mol of Na+ ions

Answer 1

Best Answer
1 mole of a substance contains 6.022x10^23 "units" of that substance.

So 0.187 mol of Na+ is 1.13x10^23 ions (6.022x10^23 x 0.187).

Answer 2

Answer : The number of ions present in 0.187 mole of sodium ions are, $1.163\times 10^{23}$

Solution : Given,

Moles of sodium ions = 0.187 moles

As we know that

1 mole of substance contains $6.22\times 10^{23}$ number of ions

So, 0.187 moles of substance contains $0.187\times (6.22\times 10^{23})=1.163\times 10^{23}$ number of ions

Therefore, the number of ions present in 0.187 mole of sodium ions are, $1.163\times 10^{23}$
