If 3.64g of sand is separated from 5.25g of a mixture of salt and sand, what is the percentage of sand in the sample?
Answer (2)
To find the percentage of sand in the original sample, we need to divide the mass of the separated sand by the total mass of the mixture containing both sand and salt, and then multiply by 100 to convert it into a percent.
We are given that the mass of sand separated from the mixture is 3.64g, and the total mass of the mixture is 5.25g. Using these values, we can set up the calculation as follows:
Percentage of sand = (Mass of sand / Total mass of mixture) x 100%
Percentage of sand = (3.64g / 5.25g) x 100%
Percentage of sand = 69.33%
Thus, the percentage of sand in the mixture is 69.33%.
The percentage of sand in the mixture is approximately 69.33%. This is calculated by dividing the mass of separated sand (3.64 g) by the total mass of the mixture (5.25 g) and then multiplying by 100%.
