The answer is 2.135 mol/Kg
Given that molarity is 2M, that is, 2 moles in 1 liter of solution.
Density of solution is 1.127 g/ml
Volume of solution is 1L or 1000 ml
mass of solution (m) = density × volume
m₁ = density × volume = 1.127 × 1000 = 1127 g
mass of solute, m₂ = number of moles × molar mass
m₂ = 2 × 95.211
m₂ = 190.422 g
mass of solvent = m₁ - m₂
= 1127 - 190.422
= 936.578 g
= 0.9366 Kg
molality = number of moles of solute / mass of solvent (in kg)
= 2 / 0.9366
= 2.135 mol/Kg
Answer:
The indepandent variable is wether its hot or cold water, so the tempurature of the water. The dependant variable is how much sugar disolves.
Explanation:
The indepandant variable is what changes or has a direct affect on the depandant. The depandant is what is being mesured or tested.
Answer:The product and reactants reach a final, unchanging level.
