English is not my mother tongue. Recently, I came across with a question which confused me in manuscript writing. Should I use "was or were" when involving volume and mass (e.g. ml and g)?
I have different idea with my co-author. He thought "was" should be used for anything described as a value of "1" (singular), otherwise use "were" for any plural. E.g:
1 mL of buffer was added... and
25 mL of buffer were added...
However, his idea cannot explain the involvement of value less than 1, e.g. 0.25 mL.
But in my opinion, these uncountable description should be standardized into "was"... (yeah though volume can actually be counted)..
Which one is grammatically correct?
Thx
