Question

calculate the formula of sodium carbonate dehydrate na2co3-10h2o

Answer 1

Molecular mass:-

$\\ \sf\longmapsto Na_2CO_310H_2O$

$\\ \sf\longmapsto 2(23u)+12u+3(16u)+10\times 2(1u)+16u$

$\\ \sf\longmapsto 46u+12u+48u+10(2+16u)$

$\\ \sf\longmapsto 96u+10(18u)$

$\\ \sf\longmapsto 96u+180u$

$\\ \sf\longmapsto 276u$
