Given:
formula of sodium carbonate =Na₂CO₃.10H₂O
=23X2+12+3x16+10[2x1+16]
=46+12+48+180
=286u
formula of sodium carbonate =Na₂CO₃.10H₂O
=23X2+12+3x16+10[2x1+16]
=46+12+48+180
=286u

Answer:
orrect option is B)
Formula unit mass of Na
2
CO
3
= 2×atomic mass of Na+1×atomic mass of C+3×atomic mass of O
=2×22.98+1×12.01+3×16
=105.97u
Formula unit mass of 10H
2
O=10×atomic mass of H
2
O
=10×18.02
=180.02u
Formula unit mass of Na
2
CO
3
.10H
2
O=105.97+180.02
=285.99u
