A. 11.0 L is the researcher's volume measurement to the SL units of liter
Explanation:
Given that a researcher recorded that the chemical reaction has water = 2.90 gallon.
We have to convert the researcher's volume into the SL units of liter.
So, we know that 1 gallon = 3.875 liters.
Then we have to convert 2.90 gallons of water in to liters.
Then , volume in L =[tex](volume\ in \ gal) \times (3.875 L/1 gal)[/tex] = [tex](2.90) \times (3.875L/1 gal)[/tex]
= [tex]11.0L[/tex]
Then the required volume in [tex]L= 11.0L[/tex]
