0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.
Step-by-step explanation:
Data given:
moles of Cd
= 0.196 Moles
Molarity of the solution = 3.91 M
Volume in litres =?
molarity is calculated by the formula:
molarity =
![(number of moles)/(volume in litres)](https://img.qammunity.org/2021/formulas/chemistry/middle-school/h2aei2g4bbjw23g3icag1zb1edjuu2j344.png)
putting the values in the above formula and rearranging it for volume:
volume =
![(number of moles)/(molarity)](https://img.qammunity.org/2021/formulas/chemistry/middle-school/nfwaggcvtuufi0gst8cizvjdk4k2ss58at.png)
volume =
![(0.196)/(3.91)](https://img.qammunity.org/2021/formulas/chemistry/middle-school/25ggf38arkokjb6s9e4o8q4h1711sjwsz5.png)
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.
