Question

find the concentration of a solution in which 155g of sodium chloride is mixed with 465ml of water?​

Answer 1

Answer:-

• mass of the Solute=155g
• Volume of the solvent=465mL=0.465L

We know

$\boxed{\sf Molarity=\dfrac{Mass\:of\: Solute}{Volume\:of\: Solvent\:in\;L}\times 100}$

$\\ \sf\longmapsto Molarity=\dfrac{155}{0.465}\times 100$

$\\ \sf\longmapsto Molarity=333.3mol/L$

Answer 2

Answer:

Concentration = No. of moles of NaCl/ Volume of solution in L

                        = 155 x 1000/465 x 58.5 = 5.69mol/L
