How many grams of sucrose must be added to 375 ml of water
toprepare a 2.75m/m percent solution of sucrose?

Answer : The mass of sucrose added to 375 mL of water must be, 10.6 grams.

Explanation :

As we are given that 2.75 m/m percent solution of sucrose. That means, 2.75 grams of sucrose present in 100 grams of solution.

Mass of solution = 100 g

Mass of sucrose = 2.75 g

Mass of water = Mass of solution - Mass of sucrose

Mass of water = 100 g - 2.75 g

Mass of water = 97.25 g

First we have to calculate the mass of water.

Density of water = 1.00 g/mL

Volume of water = 375 mL

Now we have to calculate the mass of sucrose in 375 g of water.

As, 97.25 grams of water contain 2.75 grams of sucrose

So, 375 grams of water contain grams of sucrose

Therefore, the mass of sucrose added to 375 mL of water must be, 10.6 grams.
