What is the percent by mass of NaHCO3 in a solution containing 20.0 g of NaHCO3 dissolved in 600 .0 mL of H2O?


Solutions

Expert Solution

Since density of water=1g/ml, so that mass of 600ml of water =600g

Total mass of solution=mass of NaHCO3 + mass of H2O=620g

Mass %of NaHCO3=(mass of solute/mass of solution) *100

=(20/620)*100=3.23
