Determine the relative volumes of conjugate base and weak acid that need to be taken from the respective stock solutions: (To avoid introducing rounding errors on intermediate calculations, enter your answer to four significant figures.) Total volume of buffer solution 1 L Buffer solution target pH 3.5 Stock (aq) concentration 0.100 M Stock (aq) concentration 0.300 M Show/Hide Help Previous HelpNext Help Help 1 of 5 Recall that you have a 0.100 M stock solution of the weak acid, and a 0.300 M stock solution of its conjugate base.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
