Answer : The mass of NaCl required are 14.61 grams
Explanation : Given,
Molar mass of NaCl = 58.44 g/mole
Volume of solution = 500.00 mL
Molarity of NaCl = 0.5 M = 0.5 mole/L
Molarity : It is defined as the number of moles of solute present in 1 liter of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the mass of NaCl required are 14.61 grams
Needs a question in order to know the answer.
Use the equation for uniform acceleration:
distance = Vo*t + a * t^2 / 2
As the car is initially at rest, Vo = 0
=> distance = a * t^2 / 2.
Now solve for a and replace the data of time and distance:
a = 2 * distance / (t^2)
a = 2 * 120m / (6.32s)^2 = 240m / 39.9424 s^2 = 6.009 m/s^2
Which approximates to 6 m/s^2.
So, the answer is the option B.) 6 meters / second^2
