What is the percentage of sand (SiO2) in a 2.88g of a mixture If 1.93 of sand was recovered upon separation?
huh ?
100 (1.93/2.88)
To calculate the percentage of sand (SiO2) in the mixture, you need to determine the mass of the recovered sand and divide it by the total mass of the mixture, and then multiply by 100 to get the percentage.
Given:
Mass of the mixture = 2.88g
Mass of recovered sand (SiO2) = 1.93g
To calculate the percentage of sand:
Step 1: Calculate the percentage of sand (SiO2) in the mixture using the formula:
Percentage of sand = (Mass of recovered sand / Mass of the mixture) * 100
Step 2: Substitute the given values into the formula:
Percentage of sand = (1.93g / 2.88g) * 100
Step 3: Simplify the calculation:
Percentage of sand = 0.669 * 100
Step 4: Calculate the final result:
Percentage of sand = 66.9%
Therefore, the percentage of sand (SiO2) in the 2.88g mixture is approximately 66.9%.
