What is the mass of : 10 moles of sodium sulphite `(Na_2SO_3)`?

Text Solution

Verified by Experts

Molecular mass of `Na_(2)SO_(3)=2xx23+32+3xx16`
= 46 + 32 + 48 = 126 u
`therefore` According to mole-concept,
mass of 1 mole of `Na_(2)SO_(3)` = 126 g
mass of 10 moles of `Na_(2)SO_(3)=10xx126g=1260g`
