**Laboratory Task:**
A laboratory procedure calls for preparing 510.0 mL of a 1.2 M KNO₃ solution.
**Part A:**
**Question:**
How much KNO₃ in grams is needed?
**Instructions:**
Express your answer using two significant figures.
**Input Box:**
Specify your calculated grams of KNO₃ here: [Input Box] g
---
This task requires an understanding of molarity and conversions between moles and grams. Use the formula:
\[ \text{Moles of KNO}_3 = \text{Molarity} \times \text{Volume in Liters} \]
Then convert moles to grams using the molar mass of KNO₃.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa2a8b104-43b9-4786-85b5-51d5dc6bb5cc%2F3e885d7f-1edc-43c2-b62f-c91b943980a9%2F5z7i0l_processed.jpeg&w=3840&q=75)
