From the calculations, the heat that is required is 2.1 kJ.
<h3>What is the specific heat capacity?</h3>
The term specific heat capacity has to do with the amount of heat that must be supplied to 1Kg of a substance in order to raise its temperature by 1K.
In this case;
H = mcdT
H = 100 grams * 4.18 J/gC * (25 - 20)
H = 2.1 kJ

To determine the formula units of the given compound, we need to convert from grams to moles first then convert it to formula units by using the Avogadro's number. We do as follows:
23.5 g <span>Sb2S3 ( 1 mol / 339.7 g ) ( 6.022 x 10^23 formula units / mol ) = 4.17x10^22 formula units </span><span>Sb2S3</span>
We make use of ratios to solve this question.
moles NaOH = c · V = 0.1923 mmol/mL · 26.66 mL = 5.126718 mmol
moles H2SO4 = 5.126718 mmol NaOH · 1 mmol H2SO4 / 2 mmol NaOH = 2.563359 mmol
Hence
[H2SO4]= n/V = 2.563359 mmol / 42.45 mL = 0.06039 M
The answer to this question is [H2SO4] = 0.06039 M
