How many moles of solute particles are present in 1 mL (exact) of aqueous 0.0040 M Ba(OH)2?
lidiya [134]

The number of mole of solute particles are present in 1 mL (exact) of aqueous 0.0040 M Ba(OH)₂ is 0.000004 mole

<h3>What is molarity? </h3>

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

With the above formula, we can determine the number of mole present in the solution. Detail below:

<h3>How to determine the mole of the solute in the solution</h3>
  • Volume of solution = 1 mL = 1 / 1000 = 0.001 L
  • Molarity of solution = 0.004 M
  • Mole of solute =?

Molarity = mole / Volume

Cross multiply

Mole = Molarity × volume

Mole of solute = 0.004 × 0.001

Mole of solute = 0.000004 mole

Thus, the mole of the solute in the solution is 0.000004 mole

How much energy is equal to 1 kg of mass?
EastWind [94]

This implies, for instance, that 1 kilogram of matter is equivalent to an energy E = (1 kg)×(3×108 m/sec)2 = 9×1016 kg m2/sec2. An energy of 1 kg m2/sec2 is known as 1 joule, for short.
