Aquart of liquid has a mass of 2.70 kilograms. how many quarts will it take to weigh 100.0 pounds?

Number of quartz in 100.0 pounds = 16.8 quartz

Explanation:

Step 1

Conversion of 100.0 Pounds to Kilogram

1 lb = 453.59 g

1 kg = 10^3 g

Step 2

Quartz in 45.359 g

2.70 g in a 1 quartz

= 16.7996 quartz or 16.8 quartz

i'm pretty sure its b i might be wrong though!

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
