Which is the molar mass of h2o? 10.02 g/mol 16.00 g/mol 17.01 g/mol 18.02 g/mol

Answer;

Molar mass of water is 18.02 g/mol

Explanation;

-Molar mass of a compound is determined by adding the relative atomic mass of each atom present in the compound. Molar mass of one mole of a compound, it is the weight in grams of  6.02 × 1023 atoms or molecules.

-Therefore; to calculate the molar mass of Water (H2O);  we first know the RAM of hydrogen and oxygen which are; H=1.01 and O= 16.00

Since there is two atom of hydrogen and one atom of oxygen in water;

Then; the Molar mass of water  will be; 2×1.01 + 1 ×16 = 18.02 g/mol

Molar mass:

Molar mass of any element is equal to the atomic mass of that element in the unit of grams. Molar mass is also equal to the mass of 6.02*10^23   atoms of that element.  

The water or H2O is formed from 2 mole of hydrogen and one one of oxygen

The molar mass of H = 1.008 g/ mole

The molar mass of O= 16.00g/ mole

Therefore the molar mass of water = 2* 1.008 g/ mole+16.00g/ mole

                                                    =18.02 / mole

Covalent bonds- are bonds that share electron pairs between atoms.

Ionic bonds are bonds that are made after one atom GIVES AWAY one or more electrons to the other atom.

Hydrogen Bonds- bonds between hydrogen(H) and usually O,N, or F. Hydrogen bonds are NOT TRUELY BONDS they are an ELECTROMAGNETIC ATTRACTIONS. These bonds can be Intramolecular(bonds within a molecule) or Intermolecular bonds (between two separate molecules). Individually a hydrogen bond is weak. However, hydrogen bonds can be strong in large numbers.

Metallic Bonding- occurs when metals bond with other metals their valence electrons become "delocalized," or free to move around. This delocalization forms something called the electron sea. In the electron sea, valence electrons DO NOT BELONG TO ANYONE ATOM. 

Therefore, the answer is Covalent bonds.
