A student dissolves 10 grams of sugar in enough water to make 25 ml of solution. What is the concentration of the solution

The concentration of given solution is 11.68 M.

Explanation:

Given: Mass of solute = 10 g

Volume of solution = 25 mL

Convert mL into L as follows.

Number of moles is the mass of substance divided by its molar mass. The moles of sugar (molar mass = 342.3 g/mol) is as follows.

Molarity is the number of moles of solute present in a liter of solution.

Hence, concentration of given solution is calculated as follows.

Thus, we can conclude that the concentration of given solution is 11.68 M.

your picture is not part of the scientific method.

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
