If 3.64 g of sand is separated from 5.24 g of a mixture of salt and sand, what is the percentage of sand in the sample?

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%.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
