Question

mass of solute =40 gram mass of solvent = 400 g find the concentration of the solution by mass by mass percentage​

Answer 1

• Mass of solute=40g
• Mass of solvent=400g

We know

$\boxed{\sf Mass\℅=\dfrac{Mass\;of\:Solute}{Mass\:of\:solvent}\times 100}$

$\\ \sf\longmapsto Mass\:=\dfrac{40}{400}\times 100$

$\\ \sf\longmapsto Mass\℅=10\℅$

Answer 2

00.11% is percentage.
