The Permian-Triassic extinction event<span> about 250 million years ago was the deadliest: More than 90 percent of all species perished. Many scientists believe an asteroid or comet triggered the massive die-off, but, again, no crater has been found. Another strong contender is flood volcanism from the Siberian Traps, a large igneous province in Russia. Impact-triggered volcanism is yet another possibility.</span>

What volume of water is needed for 0.196 mol of CdCl2 to prepare a 3.91 M solution? L

Brilliant_brown [7]

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Explanation:

Data given:

moles of Cd $Cl_{2}$ = 0.196 Moles

Molarity of the solution = 3.91 M

Volume in litres =?

molarity is calculated by the formula:

molarity = $\frac{number of moles}{volume in litres}$

putting the values in the above formula and rearranging it for volume:

volume = $\frac{number of moles}{molarity}$

volume = $\frac{0.196}{3.91}$

volume = 0.050 litres

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Molarity is the number of moles present in a given volume of solution which is given in litres. It is the measurement of the concentration of particular solute in a solution.
