Answer:

22.6g/mL

Explanation:

density = mass / volume

given mass of object : 142.5040

volume of object : not given however we are told that when placed inside of a cylinder with 25 mL of water the water level rises to 31.3 mL

31.3 - 25 = 6.3

So the water level rose by 6.3 mL meaning that the object has a volume of 6.3 mL

Now to find the density.

Recall that density = mass / volume

mass = 142.5040 g and volume = 6.3 mL

so density = 142.5040g / 6.3 mL = 22.6 g / ml

Ber [7]
<span> It is important to keep the NaOH solution covered at all time because sodium hydroxide is a very good remover of Carbon dioxide from the air means sodium hydroxide absorbs the carbon dioxide from the air react with that so the concentration of your solution will also change if you uncover the NaOH.
The following reaction occurs when sodium hydroxide reacts with carbon dioxide;
