Answer:
69.5%
Explanation:
We know that the total weight of the mixture of sand and salt = 5.24 g
the weight of the separated sand = 3.64 g
and the weight of the salt in the mixture = 5.24 - 3.64 = 1.6 g
So the percentage of sand in the mixture = (3.64/5.24) * 100 = 69.46
Therefore, the percentage of sand in the given 5.24 grams mixture of salt and sand is 69.5%.
