Answer:
Given
mass of solute (m) =20.5g
mass of solvent( ms) =155g
solution
malality =mX1000/mrxms
M=20.5x1000/62x155
M=2.1332
Answer:
I’m pretty sure it’s Lions sleeping after a big meal
Explanation:
Let's write the equation

According to law of conservation of mass .
- Mass of products=Mass of reactants
Let required value be x
