Answer:

Mb = 0.226 M

Explanation:

This is a acid base titration between a strong acid and a strong base, therefore, this reactions is completely done, and the reaction is the following:

NaOH + HCl -------> NaCl + H2O

We have here a 1:1 mole ratio, this means that:

1 mole NaOH = 1 mole HCl

Expressing in concentration and volume:

Mb * Vb = Ma * Va

We have concentration and volume of the acid, and the volume of the base, so we can solve for the concentration:

Mb = Ma * Va / Vb

Mb = 28.25 * 0.2 / 25

Mb = 0.226 M

This is the concentration of the NaOH solution

Four grams of hydrogen react completely with 32 grams of oxygen. Based on the law of conservation of mass how many grams of wate
neonofarm [45]

Se producirán 36 gramos de agua

Explicación: Ya que en una reacción química no puede descubrir ningún cambio en masa total de las sustancias que en ella intervienen, pues en una reacción química ni se gana ni se pierde masa.

Calculate the volume in mL of a 0.708 M KOH solution containing 0.098 mol of solute
Olenka [21]
Molarity = mol/liter

0.708M = 0.098mol/L
Rearrange to find L:
0.098mol/0.708M = .138L

For every liter there is 1000 mL:
.138L • 1000mL =138mL KOH
