Calculate the number of moles of sodium in 1.2 x 10 24 atoms of Na. Select one:
a. 3.0 x 10 2 mol Na
b. 2.0 mol Na

c. 5.0 mol Na
d. 0.66 mol Na

it can be icreased by increasing pressure.

mention the spill to the teacher clean the area and throw the broken pieces away

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

that's what i got you can count the number of atoms
