What mass of a 4.00 % NaOH solution by mass contains 15.0 g of NaOH?

fenix001 [56]

Answer:

375 g

Explanation:

Let the total mass of the solution = x g

Given that the mass of NaOH in the solution = 15.0 g

Thus, mass of the solvent = x - 15.0 g

Given that the mass % of the solution = 4 %

So,

$Mass\ percent=\frac {Mass\ of\ the\ solute}{Mass\ of\ the\ solution}\times 100$

So,

$4=\frac {15.0}{Mass\ of\ the\ solution}\times 100$

<u>Mass of the solution = 375 g</u>

How does a chemical clock work

Rudik [331]

Answer:

The reaction in this experiment is termed an iodine clock reaction, because it is the molecular iodine (I2) that undergoes the sudden concentration change. When the iodine concentration increases, it reacts with the starch in the solution to form a complex, turning it a deep blue-black color.
