Answer:
-0.93 °C
Explanation:
Hello,
The freezing-point depression is given by:
Whereas is the freezing temperature of the solution, is the freezing temperature of the pure solvent (0 °C since it is water), the Van't Hoff factor (1 since the solute is covalent), the solvent's freezing point depression point constant (in this case ) and the molality of the glucose.
As long as the unknown is , solving for it:
Best regards.
Mass determines the force of gravity like this:
If an object weight a lot it will affect the mass and gravity pulls on the object lots more when an object has lots of weight/mass.
Example: An airplane. An airplane probably weighs a ton. That is why gravity pushes it down in order for the plane to go down when it is landing or else it would be flying but never coming down. But the gravity pulling down the airplane is still there so the airplane has to be pulling the steer up in order for it to be heading straight.
Glad to help! :)
Answer:
3 you use elements instead of numbers and arrows instead of equal signs
actually it would be more like word problems you have 4 apples plus 3 oranges yields 7 apple orange things but it doesn't yield 7 of them it would be an equal ratio of moles of the fruits
4 the arrow is an equal sign
Explanation:
Answer:
0.0286 moles
Explanation:
Given mass,
Molar mass of boron, M = 10.811 g/mol
Hence, there are 0.0286 moles in given mass of boron.
