溶液稀释浓度计算公式视频(问一问:溶液稀释浓度计算公式)
1、具体的话就是这样:(1)取5ml的溶液加水稀释到25ml 1000μg/ml * 5ml / 25ml = 200μg/ml (2)再由(1)取20ml稀释到25ml 200μg/ml * 20m...

1、具体的话就是这样:(1)取5ml的溶液加水稀释到25ml 1000μg/ml * 5ml / 25ml = 200μg/ml (2)再由(1)取20ml稀释到25ml 200μg/ml * 20ml / 25ml = 160μg/ml (3)再由(2 )取20ml稀释到25ml 160μg/ml * 20ml / 25ml = 128μg/ml (4)再由(3 )取12.5ml稀释到25ml 128μg/ml * 12.5ml / 25ml = 64μg/ml (5) 再由(4)取2ml稀释到10ml 64μg/ml * 2ml / 10ml = 12.8μg/ml (6) 由(5)取5ml的溶液加水稀释到25ml 12.8μg/ml * 5ml / 25ml = 2.56μg/ml (7) 由(6)取20ml稀释到25ml 2.56μg/ml * 20ml / 25ml = 2.048μg/ml (8) 由(7 )取20ml稀释到25ml 2.048μg/ml * 20ml / 25ml = 1.6384μg/ml (9) 由(8 )取12.5ml稀释到25ml 1.6384μg/ml * 12.5ml / 25ml = 0.8192μg/ml。
