I am doing the homework for my Chem I class.  Can someone please help solve the following question in the attached screenshot picture that I took?  It's the question involving M1V1=M2V2.  Please explain step by step how you get the answer so that I can understand and learn.  Thank you so much!

You've been given a formula, can you copy it down, in our forum by posting, or maybe you want to scan a page you've written on?  What information do you know?  Can you enter those values into the formula?  What values are missing?  Does the formula answer those values for you, once you've done the math?

@OP,

Students often misapply this formula unintentionally because they choose incorrect values for V₁ or V₂.  I sometimes find drawing a picture of what is physically happening to be helpful in avoiding that particular mistake.
