Many chemical reactions take place in solutions. The concentration of a solution can be measured in mass per given volume of solution, eg grams per dm3 (g/dm3). |
|
What units are used for the measurement of concentration of a solution? Extended writing: Write instructions to another student on how to calculate the concentration, or how to rearrange the equation to calculate number of moles
Extended writing: Write instructions to another student on how to carry out a titration. Include reasons for using a burette instead |
