Answer: The percentage by volume of alcohol will be 21%.
Explanation:
Given: Volume of solute = 14.7
Volume of solvent = 70
Formula used to calculate percentage by volume is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the percentage by volume of alcohol will be 21%.
Answer:
intensity
Explanation:
Intensity has no affect on whether or not the photoelectric effect occurs. The determining property is frequency and since frequency and wavelength are inversely proportional, wavelength matters as well
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.
Answer:
The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance.
