Tim. dissolves 0.5 grams of sugar in a beaker containing 50.0g of water, as shown below. what is the mass of the solution?

a. 50.0g
b.25.0g
c.50.5 g
d.45.5g

option c = 50.5 g

Explanation:

Given data:

Mass of solute (sugar) = 0.5 g

Mass of solvent (water) = 50.0 g

Mass of solution = ?

Solution:

Formula

Mass of solution = mass of solute + mass of solvent

Mass of solution = 0.5 g + 50.0 g

Mass of solution = 50.5 g

So the mass of solution will be 50.5 g.

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
