The given question is incomplete. The complete question is :
What volume of 0.160 M solution of KOH must be added to 550.0 mL of the acidic solution to completely neutralize all of the 0.150 M hydrochloric acid?
Answer: Volume in liters to three significant figures is 0.516 L
Explanation:
To calculate the volume 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 KOH
We are given:
Putting values in above equation, we get:
(1L=1000ml)
Thus volume in liters to three significant figures is 0.516 L
We can confirm that malachite and pyrite are similar in that they are both carbonate minerals, they differ however in chemical composition and characteristics.
<h3>What is malachite and pyrite?</h3>
Pyrite is a form of iron sulfide. This mineral has come to be known as the fool's gold, for its striking resemblance to gold. Malachite, on the other hand, has been known to closely resemble emeralds and is often used as a gemstone. They are both carbonate minerals, but malachite is copper-based, giving it a different chemical composition and properties.
Therefore, we can confirm that malachite and pyrite are similar in that they are both carbonate minerals, they differ however in chemical composition and characteristics.
