What is the molarity of a koh solution if it requires 20 milliliters of 2.0m hcl to exactly neutralize 20 milliliters of the koh solution? a. 1.0m b. 2.0m c. 10m d. 20m

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

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
