See Explanation
Explanation:
The ionic compounds are; MnSO4 and LiF
The covalent compounds are; CH3NH2, PCl5 and O2
1) The formulas of the ions are;
MnSO4 - Mn^2+ SO4^2-
LiF - Li^+ F^-
The structure of each of the three covalent molecules is shown in the images attached to this answer.
2) CH3NH2 - Has a tetrahedral molecular geometry and electronic geometry
PCl5 - Has a trigonal bipyramidal molecular geometry and electronic geometry
O2 - Has a linear molecular geometry and electronic geometry.
3) CH3NH2 is sp3 hybridized
PCl5 is sp3d hybridized
O2 - is sp2 hybridized
4) MnSO4 - Manganese II sulphate
PCl5 - Phosphorus pentachloride
O2 - Oxygen molecule
LiF- Lithium fluoride
5) PCl5 - Five sigma bonds and no pi bond
CH3NH2 - 6 sigma bonds and no pi bond
O2 - 1 sigma bond and 1 pi bond
The molarity of a solution is the number of moles of a substance divided by the volume in liters prepared.
, where n is number of moles and V is the volume in liters.
In order to calculate the mass of solute we need to convert the volume and molarity to moles
Now that we have moles we use the relative formula mass of NaCO₃, We have 1 Na atom, 1 C atom and 3 O atoms, thus
