Answer:
The answer to your question is Molarity = 4
Explanation:
Data
molalidad = 4.8
density = 1.249 g/ml
molarity = ?
Process
1.- Calculate the moles of H₂SO₄
molality = moles / kilogram
Solve for moles
moles = molality x kilogram
Substitution
moles = 4.8 x 1
Result
moles = 4.8 moles
2.- Calculate the mass
- Mass of solute
Molar mass of H₂SO₄ = 2 + 32 + 64
= 98 g
98 g ----------------- 1 mol
x ----------------- 4.8 moles
x = (4.8 x 98)/1
x = 470.4 g
Total mass = 470.4 + 1000
= 1470.4 g
3.- Calculate the volume
Density = mass/volume
Volume = mass/density
Substitution
Volume = 1470.4/1.249
= 1177.3 ml
4.- Calculate molarity
Molarity = moles / volume (L)
Molarity = 4.8 / 1.177
Molarity = 4.0
