Answer:
1.5 moles of Ca²⁺ and 3 moles of NO₃⁻
Explanation:
This is the dissociation:
Ca(NO₃)₂ → Ca²⁺ + 2NO₃⁻
1.5 moles of salt will have the same moles of ion Ca²⁺ and the double of moles, of nitrate according to the equation.
Therefore will be 1.5 moles of Ca²⁺ and 3 moles of NO₃⁻
Answer:
Acetic Acid (HC2H3O2) dissolves in water, but only partially dissociates into ions.
The emission of the light waves ..................... which means that THE TROUGHS OF ONE WAVE AND THE CREST OF ANOTHER overlap.
When the trough and the crest of wave overlap, it results in constructive interference and the amplitude of the two waves are added together to form a larger amplitude.<span />
The volume of acetone, in milliliters, has a mass of 44.2 g is 55.96mL.
<h3>HOW TO CALCULATE VOLUME?</h3>
The volume of a substance can be calculated by dividing the mass by its density. That is;
Volume (mL) = mass (g) ÷ density (g/mL)
According to this question, acetone is a solvent with density of 0.7899g/mL and mass of 44.2g. The volume is calculated as follows:
Volume = 44.2g ÷ 0.7899g/mL
Volume = 55.96mL
Therefore, the volume of acetone, in milliliters, has a mass of 44.2g is 55.96mL.
