The molarity of her solution will be 1.88 M
<h3>What is Molarity ?</h3>
Molarity is defined as the number of moles of solute dissolved in per litre of solution.
Molarity of the solution = number of moles of solute / volume of solution in litre
number of moles of solute = given weight / molecular weight
= 43.3 / 45.95
= 0.942 moles
Now, lets calculate Molarity ;
Molarity of the solution = number of moles of solute / volume of solution in litre
= 0.942 / 0.500
= 1.88 M
Hence, The molarity of her solution will be 1.88 M

Answer:
Acceleration is :
a = 2.89 m/s2
Explanation:
Acceleration : It is the change in the velocity of the object per unit time.
The object starts from the rest , so the initial velocity of the object is zero.
Initial velocity , u = 0
Final velocity = 100 km/h
Change the velocity to m/s because[ time unit is in second(9.60 s)]
1 km = 1000 m
1 hour = 60 x 60 sec = 3600 sec
v = 27.78 m/s
u = 0 m/s
time = 9.60 s
The acceleration"a" is calculated using :
