Experimental Record Cup Amount of Water (mL) Amount of Salt (g) Level of Egg above Water
1 450 0 Sinks to bottom
2 450 68 2 cm
3 450 136 3 cm
4 450 272 4 cm

What was the dependent variable in this experiment?
Density of water in the cup
Level of egg above water
Amount of water in the cup
Amount of salt added

the answer is a. co2, this would be colder than the : )

explanation:

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

the maximum mass of nh3 is nh3 in grams
