What does this underline repared as a 1:1:1 mixture (by mass) of sand, salt, and term mean? Do your results for the mass of each recovered solid indicate a 1:1:1 composition of the mixture? (Firstly to mathematically calculate your own ratio divide the smallest mass into itself and then into each of the two larger masses). (5 points)

Explanation / Answer

Hi,

The underlined term means that the mass of sand, salt and salicyclic acid are equal.

i.e, say mass of sand = salt = salicylic acid = 5 g

the mass ratio will be 1 : 1 : 1.

So, you have to check that the mass of each recovered solid is same or not.

If we take 1:1:1 mole ratio then sand (SiO2), Salt (NaCl) & Salicyclic acid (C7H6O3).

So molecular weight are : sand (SiO2) - 60 g

Salt (NaCl) - 58.5 g

Salicyclic acid (C7H6O3) - 138.12 g

So the ratio will be   60 : 58: 138.12

If any doubt please ask, as there is some details from your side is missing.

Thanks.
