Question

calculate the mole mass of .Al(oh)3, Mg(oh)2,ca(oh)2, H2o,H2So4, CaSo4
​

Answer 1

Explanation:

al(oh)3. .. Al -27, O-16 , H - 1

27+3(16)+3(1) = 78gm/mol

Mg(oh)2... Mg-24., O -16 , H-1

24 + 2(16) + 2(1) =58gm/mol

Ca(oh)2..... ca- 40. , O - 16 , H - 1

40+2(16)+2(1)=74gm/mol

H2o..... H-1 , O-16

2(1)+16=18gm/mol

H2So4......... H-1 , S-32 , O -16

2(1) + 32 + 4(16)=98gm/mol

caso4......... Ca-40 , S-32 , O -16

40 + 32 + 4(16) = 136gm/mol
