Answer 1

Answer #1

Formula: V=RT/G

where, V- Volume required, R- Required concentration, T- Total volume, G- Given concentration.

Here, calculation of V is asked.

R = 250 mM , T= 250 ml , G=Molar concentraion of NaHCO₃ - 1M= 1000mM

Putting all the values in formula,

V= 250 mM X 250 ml

1000 mM

= 62.5 ml

62.5 ml of stock solution of 1M NaHCO₃ to be added in distilled water to get a 250mM of NaHCO₃
