A student carefully pipets 10.00ml of ethanol into a beaker. If ethanol has a density of 0.779g/ml, how many grams of ethanol we
re put into the beaker?
1 answer:
Answer: 7.79 grams of ethanol were put into the beaker.
Explanation:
To calculate the mass of ethanol, we use the equation:

Density of ethanol = 0.779 g/mL
Volume of water = 10.00 mL
Putting values in above equation, we get:

Thus 7.79 grams of ethanol were put into the beaker.
