Answer:
0.32M
Explanation:
Given parameters:
Number of moles of NaCl = 1.29moles
Volume of solution = 4liters = 4dm³
Unknown:
Molarity of solution = ?
Solution:
Molarity is one the ways of expressing the concentration of a solute in a solution. It is given as;
Molarity = 
The unit is given as M which is mol/dm³
Input the parameters and solve;
Molarity = 
= 0.32mol/dm³ or 0.32M
Answer:
Explanation:
Hello,
In this case, we can compute the required volume by using the ideal gas equation as shown below:
Thus, solving for the volume and considering absolute temperature (in Kelvins), we obtain:
Best regards.
i think it's I
I was confused by IV then search on gg and it said ZnSO4 should be Zn2SO4 instead but still im not sure Zn2SO4 is real
Answer:0.00000009
Explanation:
9.11 × （1/1000000000）=0.00000009
Answer:
The correct answer is B) electronegativities of the bonded atoms in a molecule of the compound .
Explanation:
When two atoms forming a bond differ in their electronegativities at that time bond polarity is generated
In simple words a bond will be polar when the bonding electrons are not equally shared by two atoms.As a result the atom attract the bonding electron pair towards itself gain partial negative charge and the other atom gains partial positive charge.
For HCl is a polar compound because H and Cl atom differ in their electronegativities,as a result the bonding electron pair is not shared equally by H and Cl atoms.
