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 = 0.196 Moles
Molarity of the solution = 3.91 M
Volume in litres =?
molarity is calculated by the formula:
molarity =
putting the values in the above formula and rearranging it for volume:
volume =
volume =
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.
Answer: C. The non metal
Explanation:-
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The nomenclature of ionic compounds is given by:
1. Positive ion or metal is written first.
2. The negative ion or non metal is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
For example: , cesium is metal having an oxidation state of +1 called as
cation and bromine
is an anion with oxidation state of -1. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
called as cesium bromide.
