Question

find the number of na+ and cl- ions present in 117g sodium chloride na =23 cl=35.5​

Answer 1

Answer:

total weight of na and cl =23+35.5

=58.5

no.of na and cl ions present in 117 g = 117 / 58.5

=2

Answer 2

The number of sodium and chloride ion present in 117 gram of sodium chloride is equal to 12.046x10²³

Explanation:

• The molecular formula of sodium chloride is NaCl. as a result of this the molecular weight of sodium chloride is 23 + 35.5 = 58.5.
• Therefore in 117 gram of sodium chloride there is 2 x avogadro number of each of the following iron which constitutes sodium chloride. = 2x6.023 x10²³ = 12.046x10²³
