Answer:

The answer to your question is 0.67 moles of Glucose

Explanation:

Data

120 g of Glucose

convert to moles

Process

1.- Calculate the molar mass of Glucose

C₆H₁₂O₆ = (12 x 6) + (1 x 12) + (16 x 6)

              = 72 + 12 + 96

              = 180 g

2.- Remember that the molar mass of each molecule equals 1 mol. Use the rule of three to find the answer.

                        180 g ------------------- 1 mol

                         120 g ------------------ x                    

                         x = (120 x 1)/180

                         x = 120/180

                         x = 0.67 moles

3.- Conclusion

120 g of Glucose are equal to 0.67 moles.

If the ionization constant of water, kw, at 40°c is 2.92 × 10-14, then what is the hydronium ion concentration and ph for an aci
charle [14.2K]

Answer is: the hydronium ion concentratio is 1.71×10⁻⁷ mol/dm³ and pH<6.76.

The Kw (the ionization constant of water) at 40°C is 2.94×10⁻¹⁴ mol²/dm⁶ or 2.94×10⁻¹⁴ M².

Kw = [H₃O⁺] · [OH⁻].

[H₃O⁺] = [OH⁻] = x.

Kw = x².

x = √Kw.

x = √2.94×10⁻¹⁴ M².

x = [H₃O⁺] = 1.71×10⁻⁷ M; concentration of hydronium ion.

pH = -log[H₃O⁺].

pH = -log(1.71×10⁻⁷ M).

pH = 6.76.

pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity an aqueous solution.
