ratio of alluminium to sulphur = 2:3

if x is amt of alluminium we need

40g *2 = 3* x

(40*2)/3=x

26.6 = x

now formulae is al2s3

hence its mass would be 27*2+32*3

which is 150

plz correct me if im wrong hope its wright fingers crossed

if x is amt of aluminium we need 40g*2=3*x

[40*2]/3=x.

now formula is al2s3

hence its mass would be 27*2+32*3

which is 150.
