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 were put into the beaker?

To calculate the mass of ethanol the student put into the beaker, you can use the formula:
Mass (g) = Volume (mL) × Density (g/mL)
Given that the density of ethanol is 0.779 g/mL and the volume is 10.00 mL, you can substitute the values into the formula:
Mass (g) = 10.00 mL × 0.779 g/mL
Now, you perform the multiplication:
Mass (g) = 7.79 g
So, the student put 7.79 grams of ethanol into the beaker.
