WebAnswer (1 of 3): Gram mole is same as mole. Molecular formula of water is H2O. You have one mole of water, H = 2 moles of atom = 2g O = 1 mole of atom = 16g So, adding the two we get the weight of one mole of water, which is 18g. Hope this helps! AG WebThe bulky CH3SO3- anions can regulate the solvation structure of Zn2+ by replacing some water molecules in the primary solvation sheath of Zn2+, thus slowing the hydrogen evolution side reactions ... The specific capacity of the assembled Zn//V2O5 cell in 3 mol L-1 Zn(CH3SO3)2 reaches 350 mA h g-1 at 0.1 A g-1, much higher than that in the ...
