What volume of ethanol in a litre (L) having a density of 0.678 g/cm3 can be poured into a graduated cylinder to give 16.28 g of alcohol?

1 answer

First, we need to convert the density of ethanol from g/cm3 to g/mL:

0.678 g/cm3 = 0.678 g/mL

Next, we can use the formula:

volume = mass / density

to calculate the volume of ethanol needed:

volume = 16.28 g / 0.678 g/mL
volume = 24.03 mL

Finally, we can convert mL to L by dividing by 1000:

volume = 24.03 mL / 1000
volume = 0.024 L

Therefore, 0.024 L of ethanol can be poured into the graduated cylinder to give 16.28 g of alcohol.
