The primary components of rocks are minerals.
Are there answer choices or is it just right it your self?
Answer:
C. 0.72 M
Explanation:
To calculate the molarity use the following equation, C=n/V
You have the molar number n which is 0.702 and the volume 0.98 L
Replace those numbers in the formula C=0.702/0.98= 0.72 M
