Concentrated sulfuric acid (18.3 M) has a density of 1.84 g/mL.
lianna [129]

The number of mole sulphuric acid in each mL of solution is 0.0183 mol/mL.

<h3>What is concentration?</h3>
  • Concentration in chemistry is calculated by dividing a constituent's abundance by the mixture's total volume.
  • Mass concentration, molar concentration, number concentration, and volume concentration are four different categories of mathematical description.  
  • Any type of chemical mixture can be referred to by the term "concentration," however solutes and solvents in solutions are most usually mentioned.
  • There are different types of molar (quantity) concentration, including normal concentration and osmotic concentration.
<h3>How is concentration determined?</h3>
  • Subtract the solute's mass from the total volume of the solution. Using m as the solute's mass and V as the total volume of the solution, write out the equation C = m/V.
  • To get the concentration of your solution, divide the mass and volume figures you discovered and plug them in.

Imagine that you are a water molecule in an ice cube. Describe what happens to you as the ice cube is heated up to a temperature
aleksley [76]
First you would melt because the melting point for ice is 0c. Then you would become warmer and warmer as the temperature rises. Lastly once the temperature reaches 100c you'll begin to evaporate as the boiling point for water is 100c.
