Answer 1

Explanation:

Hey mate

The ans is 55.55

For molarity of water= 1000/18

Answer 2

The molarity of water

Explanation:

• Molarity, also known as molar concentration, is the number of moles of a substance per liter of solution. Solutions labeled with the molar concentration are denoted with a capital M. A 1.0 M solution contains 1 mole of solute per liter of solution.

• The molarity of water depends on the temperature.

              We know, Water density is = 1 gram/mL.

              So, our liter has 1,000 grams of mass.

             Grams have a relationship with moles, via the molar mass of a molecule.

              We know , water molecules 18 g/mole. {16 (O)+1 (H) +1 (H) = 18.}

              We then take $\frac{1000}{18}$= 55.5555 moles.

              So, $H_2O$ has a molarity of 55.5
