Molekulska masa

Relativna molekulska masa je broj koji pokazuje koliko puta molekula nekog hemijskog jedinjenja ima veću masu od 1/12 atoma izotopa ¹²C. Ta mase je je ravna zbiru atomskih masa atoma koji grade molekulu.^[1]

Jedinice

SI jedinica molekulske mase je kilogram. Međutim. za proučavanje molekulske mase češće se upotrebljava jedinica atomske mase (simbol u ili Da). Primjerice, molekulska masa vode je približno:

m(H₂O)

\approx

18 u

\approx

3×10⁻²⁶kg.^[2]^[3]
