during an experiment the students were asked to prepare a 10% solution of sugar in water ramesh dissolved 10 g of sugar in 100 g of water while suresh prepared it by dissolving 10g of sugar in water to make 100 g of the solution a) are the solutions are of same concentration ?
Answers
no the solutions are not of same concentration because,
Ramesh dissolved 10 gram of sugar in hundred gram of water that is is the total weight of the solution would be 110 grams in which the concentration of sugar will be less than 10% in the solution.
where is Suresh prepared by dissolving 10 gram of sugar in water to make hundred gram of the solution that is there was 90 grams of water but he added 10 grams of sugar to make hundred grams of solution so the concentration of sugar will be e 10% in the solution.
hope it helps you ✌✌
please mark this as the brainliest answer
Answer:
no the conc. of both solutions are different
as ramesh dissolve 10 gm of sugar in 100 gm of water so the mass of total solution becomes 110 gm.
and
suresh dissolve 10 gm of water to make 100 g of solution so he takes 90 g of water in order
so. their conc. varies
hope it's helpfull
