What is associated with an object that has gravitational potential energy
Molodets [167]

Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s2.

An aqueous solution has a hydroxide ion concentration of 1.20 × 10–2 M at 25°C. Calculate the pOH of the solution.
e-lub [12.9K]
<h2>Given↷</h2>

  • [OH-] = 1.20 × 10^–2 M
  • Temperature = 25°
<h2>To find↷</h2>

  • pOH of the solution
<h2>Answer ↷</h2>

  • pOH = 1.92
<h2>Solution ↷</h2>

  • [OH-] = 1.20 × 10^–2 M
  • pOH = - log [OH^1-]
  • pOH = - log [1.20 × 10^–2]
  • <u>pOH = 1.92</u>

How many grams of glucose (C6H12O6) are contained in 555 mL of a 1.77 M glucose solution?
Alex73 [517]

176.980176 g of glucose (C_6H_{12}O_6) are contained in 555 mL of a 1.77 M glucose solution.

<h3>What are moles?</h3>

A mole is defined as 6.02214076 × 10^{23} of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

Molality = \frac{Moles \;solute}{Volume \;of \;solution \;in \;litre}

1.77 M = \frac{Moles \;solute}{0.555 L}

mole solute = 0.98235 g/mol

Moles  = \frac{mass}{molar \;mass}

0.98235 g/mol  = \frac{mass}{180.16 g/mol}

mass = 176.980176 g

Hence, 176.980176 g of glucose (C_6H_{12}O_6) are contained in 555 mL of a 1.77 M glucose solution.
