Answer: 7.79 grams of ethanol were put into the beaker.
Explanation:
To calculate the mass of ethanol, we use the equation:
![\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}](https://tex.z-dn.net/?f=%5Ctext%7BDensity%20of%20substance%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20substance%7D%7D%7B%5Ctext%7BVolume%20of%20substance%7D%7D)
Density of ethanol = 0.779 g/mL
Volume of water = 10.00 mL
Putting values in above equation, we get:
![0.779g/mL=\frac{\text{Mass of ethanol}}{10.00mL}\\\\\text{Mass of ethanol}=(0.779g/mL\times 10.00mL)=7.79g](https://tex.z-dn.net/?f=0.779g%2FmL%3D%5Cfrac%7B%5Ctext%7BMass%20of%20ethanol%7D%7D%7B10.00mL%7D%5C%5C%5C%5C%5Ctext%7BMass%20of%20ethanol%7D%3D%280.779g%2FmL%5Ctimes%2010.00mL%29%3D7.79g)
Thus 7.79 grams of ethanol were put into the beaker.
