Step 1
Answer
To find the concentration in moles per litre, follow these steps:
Calculate the volume of isopropyl alcohol in 100 cm³: The sanitizer is 70% (v/v), hence:
Calculate the volume of isopropyl alcohol in 1 litre:
Calculate the mass of isopropyl alcohol: Using density (0.8 g/cm³):
Calculate the number of moles of isopropyl alcohol: The molar mass of isopropyl alcohol (C₃H₈O) is approximately 60.094 g/mol. Thus:
Thus, the concentration of isopropyl alcohol is approximately 9.33 moles per litre.
