Question

Quick dilution questions!! Will fan and medal!!

1) It takes how many mL of 10mg/mL Sucrose solution to get 10mL of 1mg/mL.

For this one I got the answer being 1 mL because (v1)(c1)=(v2)(c2). The answer seems too easy and I feel like it is trying to trip me up.

2) How many mg of NaCl is required to make 0.1 L of 5mg/mL salt solution.

I think the wording is throwing me off. I'm tired and my brain isn't switching the words around like it usually does.

Thank you ahead of time!!

This is the EXACT same question btw. Same numbers, just different names of things.
