This is because the FINAL volume will then be 25 uL. 256 C 2 = (C 1 V 1 )/V 2. Here is the first way to solve this problem: (3.55) (0.250) + (5.65) (x) = (4.50) (0.250 + x), Where x is volume of 5.65 M HCl that is added vUcf0c+m71KsxobDmgRtEAg6whihA3R07Lucz5oiPHGpg6Sd3Kqzn5+H1W17hhYWL67y2C51hDg9 C 1 = concentration of starting solution. et9T/wDyxzv86z/yCSlet9T/APyxzv8AOs/8gkpXrfU//wAsc7/Os/8AIJKV631P/wDLHO/zrP8A / GDMH3JUVcQdzJ9PIx7ccXembWOYHtcA5u4Ebh5hKiriDgf8ANY/+XWV/25/5klRVxBX/ADWP/l1l xmp.iid:E6266C32FE236811871FF8EAC8023FA4 / / wqA5pkEMEghJTfSUpJSklKSUpJSklKSUpJSklKSUpJSklKSUpJTXyf57E/44/wDnq5JSun/8n43/ SEjIj6M/MZsMsccQlYB+YtvL670/H6nh9Qwsn7QyuluLkVCt7ZYNxLveBP0uE2OKRiQR4s2XnMUc /;/metadata saved %PDF-1.6 % False mrUihSSlJKUkpSSlJKUkpSSlJKUkpSSlJKUkpi76TP638CgUjYvQ431I6tbj1WttxwHsa4S58wQD P2mv/VzP/JIqs9lDJYTAEk/ym/8AkklWezM2ECSxwA5Mt/8AJJKs9mH2mv8A1cz/AMkkqz2V9pr/ Several different dilutions can be prepared from the stock solution by adding the desired solvent in a specific volume. a8gAkeMuTo3jycPQseYx5nlzkIqUTr4p+pZh+qzaOndNrrbkGptmRkOaHOc50iBPbRNhH3rMmTPl xmp.iid:90C8F6F4FE236811871FF8EAC8023FA4 You have a 2 mg/mL stock. 3. For example, if you want to calculate the final volume of a solution you would change the formula to:if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'toptipbio_com-medrectangle-3','ezslot_1',108,'0','0'])};__ez_fad_position('div-gpt-ad-toptipbio_com-medrectangle-3-0'); Or, if you want to calculate the initial starting concentration of a solution you would use: Once you understand the equation, it will become accustomed to your everyday lab work.
