Answer:
Distance cover by school bus = 149.5 miles
Explanation:
Given:
Velocity of school bus = 65 mph
Time taken by school bus = 2.3 hours
Find:
Distance cover by school bus
Computation:
Distance cover = Velocity x Time taken
Distance cover by school bus = Velocity of school bus x Time taken by school bus
Distance cover by school bus = 65 x 2.3
Distance cover by school bus = 149.5 miles
Answer : The number of moles of solute
is, 0.0788 moles.
Explanation : Given,
Molarity = 0.225 M
Volume of solution = 0.350 L
Formula used:
![\text{Molarity}=\frac{\text{Moles of }Ca(OH)_2}{\text{Volume of solution (in L)}}](https://tex.z-dn.net/?f=%5Ctext%7BMolarity%7D%3D%5Cfrac%7B%5Ctext%7BMoles%20of%20%7DCa%28OH%29_2%7D%7B%5Ctext%7BVolume%20of%20solution%20%28in%20L%29%7D%7D)
Now put all the given values in this formula, we get:
![0.225M=\frac{\text{Moles of }Ca(OH)_2}{0.350L}](https://tex.z-dn.net/?f=0.225M%3D%5Cfrac%7B%5Ctext%7BMoles%20of%20%7DCa%28OH%29_2%7D%7B0.350L%7D)
![\text{Moles of }Ca(OH)_2=0.0788mol](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20%7DCa%28OH%29_2%3D0.0788mol)
Therefore, the number of moles of solute
is, 0.0788 moles.
