< Question 23 of 26 > An unknown metal sample with a mass of 14.8 g was obtained. The samp several metals are listed in the table. Metal Density (g/mL) aluminum 2.70 iron 7.87 cobalt 8.90 copper 8.96 gold 19.3 What is the possible identity of this metal sample?

b. examine and describe cells

can you list the answers so i can answer

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
