Mass of carbon / Mass of acetone x 100% = Percentage by mass Carbon<span>.
</span>Take the formula mass of acetone, <span>and then do the calculation.</span>
The purpose is to help you estimate the total distance because a map is zoomed out so they need to scale it down so its small and the scale helps make the distance accurate.
Answer:
Amount of sucrose required = 278.85 g
Explanation:
(w/v)% = 39.0 %
Volume of the solution = 715 mL
39% (w/v) means 39 g of sucrose present in 100 mL of the solution.
Using unitary method,
For making 39% solution,
100 mL solution requires 39 g of the sucrose
therefore, 715 mL solution requires:
= 278.85 g
