One millimole of C_aSO_4 weighs _______ . (Ca = 40, S = 32, O = 16)

1.	One millimole of C_aSO_4 weighs _______ . (Ca = 40, S = 32, O = 16)
Answer» 136 G 13.6 g 0.136 g 0.0136 g Solution :ONE mole of `CaSO_4` = gram molecular weight of `CaSO_4` = 40 + 32 + 64 = 136 g One millimole of `CaSO_4` `= 136xx10^(-3) = 0.136 g`
