If one molecule of glucose (C6H12O6) reacts completely with three molecules of oxygen (O2), what is the TOTAL number of atoms th
USPshnik [31]

Answer;

30 atoms

Explanation;

When glucose, C6H12O6, reacts with oxygen it produces carbon dioxide and water. If a molecule of glucose reacts completely with three molecules of oxygen, then 30 atoms would be produced because there are 24 atoms in glucose and 6 atoms in oxygen molecules.

The equation for the reaction would be;

C6H12O6 + 6O2(g) → 6CO2(g) + 6 H2O(l)

What is the molality of a solution in which 0.42 moles aluminum chloride has been dissolved in 4200 water ?
madreJ [45]

Answer:

0.1 M

<h3>Explanation:</h3>
  • Molarity refers to the concentration of a solution in moles per liter.
  • It is calculated by dividing the number of moles of solute by the volume of solvent;
  • Molarity = Moles of the solute ÷ Volume of the solvent

<u>In this case, we are given;</u>

  • Number of moles of the solute, NH₄Cl as 0.42 moles
  • Volume of the solvent, water as 4200 mL or 4.2 L

Therefore;

Molarity = 0.42 moles ÷ 4.2 L

            = 0.1 mol/L or 0.1 M

Thus, the molarity of the solution will be 0.1 M
