How many grams of sodium hydroxide (NaOH) are required to
dissolve in 232 g of water to make a
2.88 m solution?
[?]g NaOH
Molar mass of NaOH: 39.998 g/mol

Explanation:

Hello,

In this case, given the molality of the solution which is 2.88 m (mol/kg) we can compute the moles of sodium hydroxide that are dissolved in the 232 grams of water (0.232 kg) as follows:

Then, by using the molar mass of sodium hydroxide we compute the grams:

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
