Scientists identify an ammonia molecule as NH3. How many
hydrogen atoms are there in
one molecule of ammonia?
A. one
B. three
C. four
D. There is not enough
information to determine
the 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

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
