Cuantos gramos de hidróxido de calcio se necesitan para preparar 875ml de solución al 2M​
PtichkaEL [24]

Answer:

129,66 g

Explanation:

Desde,

Número de moles = concentración * volumen

concentración = 2 M

volumen = 875 ml

Número de lunares = 2 * 875/1000

Número de lunares = 1,75 moles

Número de moles = masa / masa molar

masa molar de hidróxido de calcio = 74.093 g / mol

1,75 moles = masa / 74,093 g / mol

masa = 1,75 moles * 74,093 g / mol

masa = 129,66 g

A bottle of soda has a PH of 3.
BaLLatris [955]

Answer:

The new pH of the solution = 6

Explanation:

Given

pH of bottle of Soda is 3

As we know that

pH = -log [H+]

We will derive the hydrogen ion concentration when pH is 3

3 = - log [H+]

Taking anti-log on both the sides, we get -

H+ ion is equal to 10^{-3}

When the hydronuim ion concentration reduces by \frac{1}{1000} of the original concentration, the new hydrogen ion concentration becomes

\frac{1}{1000000} = 10^{-6}

The new pH is

= - log [ 10^{-6}]\\= 6
