Question

Check the atomic weight of Al2(SO4)3

Answer 1

Answer:-

We have to find molecular mass

$\\ \sf\longmapsto Al_2(SO_4)_3$

• Al=27u
• S=32u
• O=16u

$\\ \sf\longmapsto 2(27u)+3\times (32u+4\times 16u)$

$\\ \sf\longmapsto 54u+3(32u+64u)$

$\\ \sf\longmapsto 54u+3(96u)$

$\\ \sf\longmapsto 54u+288u$

$\\ \sf\longmapsto 342u$
