The volume of the soft drink solution in milliliters that contains 102.5 g of sucrose is 11.93mL.
<h3>How to calculate volume?</h3>
The volume of a solution can be calculated by dividing the mass by the density. That is;
Volume = mass/density
According to this question, a soft drink contains 12.1% sucrose (C12H22O11) by mass. This means that the mass of the sucrose is
12.1/100 × 102.5 = 12.40g of sucrose
Volume = 12.40g ÷ 1.04g/mL
Volume = 11.93mL
Therefore, the volume of the soft drink solution in milliliters that contains 102.5 g of sucrose is 11.93mL.

Standard enthalpy change of neutralization is the enthalpy change when 1 mole of water is produced by the reaction of an acid and a base under standard conditions.
Enthalpy change of neutralization:
- Every time enthalpy change of neutralization is calculated, one mole of water is produced.
- Heat is released when an acid and an alkali react, hence enthalpy changes of neutralization are always negative.
- The values are always quite comparable for reactions involving strong acids and alkalis, falling between -57 and -58 kJ mol-1.
- If the reaction is the same in each case of a strong acid and a strong alkali, the enthalpy change is similar.
