<span>10 g of hexane has a greater volume than 10 g of toluene.
volume of hexane = 15.27 mL
volume of toluene = 11.53 mL
First, look up the density of hexane and toluene.
hexane = 0.6548 g/mL
toluene = 0.867 g/mL
Since hexane has the lower density, the same mass of hexane will have a higher volume than the same mass of toluene. No need for you to actually calculate the volume for the first part of the question.
However, the 2nd part of the question does require you to calculate the volume. That is a simple matter of division.
volume of hexane = 10 g / 0.6548 g/mL = 15.27 mL
volume of toluene = 10 g / 0.867 g/mL = 11.53 mL</span>
The rate of change in velocity<span> is called acceleration.</span>
The first thing we need to do here is to recognize the unit of molarity and the units of the given percentage of nitric acid.
Molarity is mol HNO3 / L of solution. This is our aim
The given percentage is 0.68 g HNO3/ g solution
multiplying this with density to convert g solution into mL solution and dividing with the molecular weight of HNO3 (63 g/mol) to convert g HNO3 to mol. Therefore we obtain
0.016 mol/ mL or 16.23 mol/ L (M)
Answer: Fluorine has a stronger "pull" on its electrons
Ionization Energy is a measure of how much energy it takes to "pull" an electron off of an element
