Questions & Answers about Tarkkuus kärsii varmasti, jos reagenssia haihtuu vajaat kolme grammaa.
Why is vajaat in the plural while kolme is singular?
This is exactly the trick with measurement approximations! In Finnish, the adjectives vajaat (just under / short of) and reilut (a good / just over) are idiomatically put in the plural when they precede a numeral in the nominative singular. It is a fixed pattern you simply have to memorize.
Does the plural vajaat affect the verb form of haihtuu?
Why is reagenssia in the partitive case?
This clause functions similarly to an existential sentence. The grammatical subject is the quantity itself (vajaat kolme grammaa). The substance that is evaporating is treated as an uncountable mass attached to that quantity, so it takes the partitive case (reagenssia).
