what volume (in ml)of 0.2M H2SO4 solution should be mixed with the 40ml of 0.1M NaOH SOLUTIONsuchthat the resulting solution has concentration of H2SO4 as (6/55)M |

Answer» Solution: We know that resultant molarity is given by Resultant Molarity = (M1V1+M2V2)/(V1+V2) we have M1 = 0.1, V1 = 40ml = 0.04 litre M2 = 0.2, V2 = ? Now putting the values in above formula we get, (0.1x0.04 + 0.2xV2)/0.04+V2 = 6/55 => 0.004+0.2V2 = (0.24+6V2)/55 => 0.22+11V2 = 0.24+6V2 => 5V2 = 0.02 => V2 = 0.004 litre Hence, V2 = 0.004 litre or 4ml |
