Remember what the equation is:
MOLARITY = MOLES SOLUTE/LITERS OF SOLUTION
Solute = what you dissolve (in our example, glucose)
LET
Solvent = what does the dissolving (in our example, water)
ments
Solution = the mixture of the two (sugar water!)
Let's start with an easy example. Suppose you weighed out 25 g of glucose
(CH20)
1. How many moles of glucose did you weigh out?
2. If you added enough water to make 1 liter of solution, what would be the
molarity of the solution you made?
3. Suppose instead you took 25 g of glucose and only added enough water to
make 500 mL of solution. What would be the molarity of that solution?
4. Lastly, what if you took 25 g of glucose and added enough water to make 2
liters of solution. What would the molarity be?

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
