Answer:
Solute = 5 mL; solution = 250 mL
Explanation:
The formula for percent by volume is
If you have 250 mL of a solution that is 2 % v/v,
If there is no change of volume on mixing,
Volume of solution = 250 mL
-Volume of solute = <u> </u><u>5</u><u> </u>
Volume of solvent = 245 mL
I believe the correct answer from the choices listed above is option C. The type of substances that has <span>chemical bonds that are not directional and valence electrons that move freely between the atoms are metals. Hope this answers the question. Have a nice day.</span>
Answer:
8 cm3
Explanation:
The volume of this irregular solid will calculated as the difference between the final volume and the initial volume;
The final volume of the water and the solid is 25 ml
The initial volume of the water alone was 17 ml
The volume of the irregular solid is thus approximately;
25 - 17 = 8 ml
We then use the conversion;
1 cm3 = 1 mL
Thus the volume of the solid is 8 cm3
