Glucose is a sugar that is found abundantly in nature. What is the percent by mass of a solution made by dissolving 163g of glucose in 755 gram of water? Do you need to know the formula of glucose? why Or why not?
The formula of glucose is not needed to solve this problem.
To find the percent by mass of a solution, we need to divide the mass of the solute (glucose) by the mass of the solution (glucose + water) and multiply by 100.
Percent by mass = (mass of solute / mass of solution) x 100
In this case, the mass of solute (glucose) is 163g, and the mass of solution (glucose + water) is 163g + 755g = 918g.
Percent by mass = (163g / 918g) x 100 = 17.75%
Therefore, the percent by mass of the solution is 17.75%.
To calculate the percent by mass of a solution, you need to know the mass of the solute (glucose) and the mass of the solution (glucose + water).
The formula of glucose, C6H12O6, is not necessary to solve this problem, as we only need the mass of the solute and the mass of the solution. The percent by mass can be calculated using the following formula:
Percent by mass = (mass of solute / mass of solution) x 100
In this case, the mass of the solute (glucose) is 163g, and the mass of the solution (glucose + water) is 163g + 755g = 918g.
Plugging these values into the formula:
Percent by mass = (163g / 918g) x 100 = 17.77%
Therefore, the percent by mass of the solution made by dissolving 163g of glucose in 755g of water is approximately 17.77%.
