17.5g的zn和H3PO4反响,然后生成Zn3(PO4)2和氢气.他先让我求需要多少H3PO4.我算完了.第二问说如果H3PO4是3mol的溶液那我需要多少升,就用第一问的答案
原题是if 17.5g of zinc metal are reacted with phosphoric acid, h3po4(aq),then zinc phosphate,zn3(po4)2 (aq), and h2 are produced,
1.how many moles of phosphoric acid are required这个我会
2.if the phosphoric acid is a 3.00molar solution, how many liters are needed?详细解释下 3.00molar solution.
