How can I improve the amount of time that I can think about a math problem before losing concentration ?
Ammonia : I have Ammonium Hydroxide Solution with concentration of about -LSB- math -RSB- 28 \ % \ \ require -LCB- mhchem -RCB- \ ce -LCB- NH3 -RCB- -LSB- / math -RSB- in -LSB- math -RSB- \ ce -LCB- H2O -RCB- -LSB- / math -RSB- , how can I calculate the concentration of -LSB- math -RSB- \ ce -LCB- NH4 + -RCB- -LSB- / math -RSB- in this solution ?
