Answer:
A) 60
Explanation:
Given data:
Distance traveled by car = 210 km
Time taken = 3.5 hour
Speed of car = ?
Solution:
Formula:
S = d/t
s = speed of car
d = distance
t = time
by putting values,
s = 210 km / 3.5 hour
s = 60 km/hour
I would go with pure water
Answer: The molarity of the malonic acid solution is 0.08335 M
Explanation:
To calculate the molarity of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Thus the molarity of the malonic acid solution is 0.08335 M
