HI
YOUR ANSWER
============
The molar mass of sodium carbonate is 105.987 g/mol
→Molar mass of Na2CO3=
=====================================
(2×22.98976928g/mol Na)+(1×12.0107g/mol C)
+(3×15.999g/mol O)=105.987 g/mol Na2CO3
===================================
HOPE THIS HAS CLEARED YOUR DOUBT:-)

atomic mass of Na is 23 u
C is 12 u
O is 16 u
now
in one mole of Na2CO3
there is two atoms of Na and 1 atom of C and 3 atoms of O
now
molecular mass of Na2CO3
=2 (mass of Na)+atomic mass of C + 3 (atomic mass of O)
=2 (23)+12+3 (16)
=46+12+48
=106 u
hope it helps

welcome
u have written the wrong atomic mass of C. it is 12 not 14. so correct it by editing it
oh sorry
no problem
u r good
thank u for appreciation
ur welcome
by the way in what aspect I m good ?
in ur writing style and explaining the question in a good manner
