Convert 200.0 grams of H2O to molecules. Show all work

1. 19.6 g

2. 5.71 moles

3. 11.1 moles

Explanation:

In order to convert the moles to grams, either the grams to moles we need the molar mass of the compounds:

Let's make the conversions:

1. 0.2 mol . 98g / 1 mol = 19.6 g

2. 102.8 g . 1 mol / 18 g = 5.71 moles

3. 200 g . 1 mol / 18 g =  11.1 moles

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

what is the question here. i think you messed up.
