Question

find the mass of glucose present in 3m of solution​

Answer 1

$❥\huge\mathfrak\pink[ANSWER]❥$

Correct option is A 18 g

Given molarity of the solution =0.2

Volume of solution =200ml=0.2 L

Molarity=Volume in litresMoles of solute

Moles of solute =0.2×0.2=0.04

No. of moles=Molar massGiven mass

Molar mass of C6H12O6=6×12+12+6×16=180g

Mass of glucose in the solution = 180×0.04=7.2g

Answer 2

Answer:

Given molarity of the solution =0.2

Volume of solution =200ml=0.2 L

Molarity=

Volume in litres
