Answer to Question #246448 in General Chemistry for lei

Question

concentration 1is equal 3.975 m, concentration is equal 6.532, quantity 2 is equal to 4.937 kg solvet and the mixed solution is equal to 5.421, find the quantity 1 and its unit

Answer 1

M₁V₁ = M₂V₂

Molality = moles/Kg of solvent

5.421=4.937

x. =6.532

4.937x =5.421*6.532

4.937x =35.41

x =35.409/4.937

x=7.17

the quantity 1  =7.17 kg
