Magnesium bromide pentahydrate. (MgBr2.5H2O)

NB 'mgbr25h2o'. is incorrectly written. When writing chemical formula a one-letter symbol is always a capital letter .e.g. 'H' hydrogen and 'O' oxygen. A two-letter symbol is always written ; first letter is a capital letter and the second letter is small/lower case. e.g. 'Mg' Magnesium and 'Br' Bromine.

Prefixed numbers (Molar ratios) are full script. post script numbers indicating the number of a given atom are written subscript ; unfortunately I cannot show it on Answers. A 'Full stop/Period' is always placed between the given compound and the hydrate number.
