Question

Explain why 5.00 grams of salt does not contain the same number of particles as 5.0 grams of sugar​

Answer 1

Answer:

5.00 grams of salt contain more particles than 5.0 grams of sugar​

Explanation:

Salt = NaCl

Molar mass = 58.45  g/mol

Sugar = C₁₂H₂₂O₁₁

Molar mass = 342.3 g/mol

Sugar's molar mass is higher than salt.

So 1 mol of sugar weighs more than 1 mol of salt

But 5 grams of salt occupies more mole than 5 grams of sugar

5 grams of salt = 5g / 58.45 g/m = 0.085 moles

5 grams of sugar = 5g/ 342.3 g/m = 0.014 moles

In conclusion, we have more moles of salt in 5 grams; therefore there are more particles than in 5 g of sugar.
