Question

calculate the mass percent of sugar in its solution which contains 45 gram of sugar and 255 gram of water​

Answer 1

Answer:

15%

Explanation:

mass percentage = mass of solute by mass of solution

mass of solution = mass of solute + mass of solvent

m of solute = 45 gm and mof solvent = 255 gm

m of solution = 255 + 45 = 300gm

mass percentage = 45   × 100

                                300

                              =4500/300=15%

Answer 2

Hi, dear

Here is your answer!!

Answer:

15%

Explanation:

Given: Mass of solute (sugar) = 45 gram

Mass of solvent (water) = 255 gram

Mass of solution = Mass of solute + Mass of solvent

= 45g + 255g

= 300g

Mass percentage of sugar in its solution:

Mass % = Mass of solute/ Mass of solution

= 45g / 300g ×100

= 45/300×100

= 45/3

= 15%

Hope this help u!!
