Question

SE DESEA OBTENER UNA SOLUCION 0.3 MOLARIDAD DE HIDROXIDO DE POTASIO DISOLVIENDO 60 GRAMOS DE HIDROXIDO -¿QUE VOLUMEN DE SOLUCION SE OBTENDRA QUIMICA

Answer 1

Answer:

3.56L will be the obtained volume

Explanation:

0.3 M → Molarity

These are the moles of solute (for this case, the solute is KOH) that are contianed in 1L of solution

We dissolved 60 g of solute, so let's determine the moles:

60 g . 1 mol/ 56.1 g = 1.07 moles

Molarity(mol/L) = Mol / Volume(L)

Let's replace data: 0.3M = 1.07 mol / Volume(L)

0.3 mol/L = 1.07 mol / volume

Volume = 1.07 mol / 0.3mol/L = 3.56 L
