Barium oxalate is used as a colorant to produce the green color in fireworks. imagine that you have been assigned to prepare barium oxalate by reacting barium hydroxide octahydrate (ba(oh)2·8h2o) with oxalic acid dihydrate (h2c2o4·2h2o). find the number of grams of oxalic acid dihydrate that would be required to completely react with 5.3 g of barium hydroxide octahydrate. use correct significant figures. do not include a unit with your answer or it will be counted wrong.

h2c2o4·2h2o 126.07 g/mol
h2c2o4 90.03 g/mol
ba(oh)2·8h2o 315.46 g/mol
ba(oh)2 171.34 g/mol
