A solution contains 20g of solute in 180g of solvent. If the solvent is water, what is the concentration of the solution in terms of mass by mass percentage
A. 11.%
B. 22.2%
C. 10%
D. 20%
Please show working
Concentration of a solution:
"m\/m\\space=\\frac{mass\\space of \\space solute}{mass\\space of\\space solution}\u00d7100"
Mass of solutions=mass of solute + mass of solvent =20g+180g = 200g
"m\/m\\space=\\frac{20}{200}\u00d7100=10%"
