Answer: The molar concentration of acetic acid in the vinegar is 0.539 M.
Explanation:
The formula used is:
where,
and 
are the concentration and volume of base.
and 
are the concentration and volume of an acid.
Given:
Molar concentration of NaOH = 0.1798 M
Volume of NaOH = 30.01 mL
Volume of acetic acid = 10.0 mL
Now putting all the given values in the above formula, we get:
Thu, the molar concentration of acetic acid in the vinegar is 0.539 M.

Answer:
less then 50
Explanation:
please tell me if i right
Moving in a direction is called having a "velocity". A velocity is just having a speed, but only in one direction. Because of a thing called "Newton's First Law", in order to change the speed or direction of an object, it must be accelerated, which is a fancy way of saying it's velocity must change with respect to time, meaning that for every second it travels while be accelerated, its velocity will change by this much, either in speed or direction or both. Due to "Newton's Second Law", and acceleration is gained by applying a force. Using the equation "F = ma" where F is force applied, m is mass of the object, and a is the acceleration of the object. This means that it is harder to move things with more mass.
Specifically relating to change in direction, force is also a thing which has a direction. A force can be any size, and also have any direction. When a force is applied in a certain direction, the acceleration of the object will be in the same direction of the force.
