Question

A solution of sulphuric acid has a concentration 0.5~mol/din^{3} how many moles are present in 25cm^{3}

Answer 1

[AI-generated answer — Bot GPT 3.5]

To determine the number of moles present in 25 cm³ of a 0.5 mol/dm³ solution of sulfuric acid, we need to convert the volume from cubic centimeters to cubic decimeters.

1 cm³ = 1/1000 dm³

Therefore, 25 cm³ = 25/1000 = 0.025 dm³

Now we can calculate the number of moles using the formula:

moles = concentration * volume

moles = 0.5 mol/dm³ * 0.025 dm³

moles = 0.0125 moles

Therefore, there are 0.0125 moles of sulfuric acid present in 25 cm³ of the solution.
