<h3>Given equation:-</h3>
<h3>BALANCED EQUATION:-</h3>
<u>Answer:</u> The molarity of solution is 0.34 M.
<u>Explanation:</u>
- To calculate the number of moles, we use the equation:
<u>For lead chloride:</u>
Given mass of lead chloride = 18.86 g
Molar mass of lead chloride = 278.1 g/mol
Putting values in above equation, we get:
- For the balanced chemical equation:
By Stoichiometry of the reaction:
1 mole of lead chloride is formed by 1 mole of lead nitrate
So, 0.068 moles of lead chloride will be formed from = of lead nitrate
- To calculate the molarity of solution, we use the equation:
We are given:
Volume of solution = 200 mL = 0.200 L (Conversion factor: 1 L = 1000 mL)
Moles of lead nitrate = 0.068 moles
Putting values in above equation, we get:
Hence, the molarity of solution is 0.34 M.
All compounds are molecules because a molecule is 2 or more substances/elements combined and a compound is 2 or more elements combined. But not all molecules are elements because some molecules are just combined substances with no elements combined at all.
Why does magma composition change during fractional crystallization? Different elements in the magma form crystals at different rates, leaving behind more of the unused elements. ... The crystals are denser than the magma.
C. They both can serve as storage within the cell Rese.
