Total weight of the mixture of sand and salt = 5.25 g Weight of sand separated = 3.64 g Weight of the salt in the mixture = (5.25 - 3.64) g = 1.61 g Then the percentage of sand in the sample = [(3.64/5.25) * 100] percent = 69.33% So the percentage of sand in the total mixture of sand and salt is 69.33%.
