2025年2月17日 · To prepare a 2M HCl solution, you would mix concentrated HCl (usually 12M) with water in a 1:6 ratio. For example, to make 1L of 2M HCl solution, you would mix 167 mL of concentrated HCl...

Intratumoral gold-doxorubicin is effective in treating melanoma in mice. Intratumoral injection of ultra-small gold nanoparticles (AuNPs) conjugated to doxorubicin (Au-Dox) is effective against both murine B16 and human SK-MEL-28 tumors in mice. Au-Dox suppresses growth of B16 tumors in immunocompetent mice by >70% for at least 19 days. In.

配制 1 M HCl 就需要一共 12 L 的溶液，也就是说我们取的浓盐酸加入到 11 L 的水中就能够得到 1M HCl。 市售浓盐酸的质量百分数为 36%～38%，我们就取个平均数37%，已知浓盐酸的密度 …

2020年4月14日 · 大家好，近期收到一些朋友询问“2mol/l的盐酸怎么配”的问题，今天我来分享下我的经验，希望能够帮助到大家。 首先，必须知道用于稀释的盐酸的浓度度是多少，假设使用的是36.5%左右的盐酸,这种盐酸的物质的密度为1.19g/ml。 其次，根据溶液稀释公式：c1v1=c2v2，算出需要盐酸的物质的量＝0.2X1＝0.2molv= (0.2*36.5)/ (36.5%*1.19)=16.8ml。 然后，我们在用量筒取出16.8ml的量倒入烧杯中，用适量（20~30mL）蒸馏水稀释，待到冷却后，用玻璃棒引 …

Suppose you are going to prepare 250.0 mL of 2 M HCl. Use a graduated pipette to transfer 40.4 mL of 38% HCl to a 250-mL volumetric flask. Add distilled water to the mark of the volumetric flask. Stopper the volumetric flask and mix well the solution.
