Explanation:
When electrons transfer from one atom to another, both atoms become <u>_ions_</u>___ and are held together by a(n) _<u>ionic</u>__ bond. When electrons are shared between atoms, a(n) <u>covalent</u>___ bond forms between the atoms, and the joined atoms become a(n) __<u>molecules</u>_.
Answer:
To calculate the molarity of a solution it is necessary to know
- Moles of solute, or mass
- Volume of solution
Explanation:
Molarity means moles of solute, in 1L of solution.
If you firstly know the mass of solute, you can turn into moles like this:
Mass of solute / Molar mass of solute = Moles
Also, you should know the volume.
If those moles are in a certain volume, in 1L (or 1000 mL), how many moles, do you have. You should make a rule of three.
Molarity = moles / L
mmoles / mL
Answer:
method
Explanation:
Fusion
It is the one that make the most sense
Moles of ZnSO4 = Mass/Mr
= 2/(65.4 + 32.1 + (16 x 4))
= 0.012383.... mol
Since there is no chemical equation provided, I will assume that the ratio of ZnSO4:Li2CO3 is 1:1
Therefore there are 0.012383 mil of Li2SO4 as well
So the mass would be Moles x Mr = 0.012383.... x ((6.9 x 2) +32.1 + (4x16))
= 1.360 g of Li2SO4 produced
