If 3.5 g of NaCl is added to 100 mL of water to form a salt solution, what is the solute? 1.water
2.salt solution
3.NaCl
4. all of the above
Its Pre ap Chem

Thats pretty easyIts C.

Explanation:

Look at it like this, so 3.5g of NaCI is added to 100 mL of water right? So then you know that solvent is the substance that the solute was dissolved in. So now what does solute mean and what is the solute?

Solute: In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.

In this case, the solute is the salt because it was being dissolved in the water.

Hope this helps!

*tilts head* sounds more like a statement

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
