The cube above has a weight of 8.22kg. Converting kilograms to grams: 8,220g * .03527396g/1kg = 300,484.09g. The mass of the cube is approximately equal to 300 kg or 660 lbs (not including the supporting stand).

The atomic symbol Ti stands for titanium, which is also represented as Ti on the periodic table of elements, with the atomic number of 22; its atomic weight is 47.867; its melting point is 1660 degrees Celsius (3080 degrees Fahrenheit); it has an abundance rank of 8 out of 56; and its density is 4.51 grams/cm3. The melting point and boiling point would change if a different crystal structure was assigned to titanium.

Titanium Atoms
The volume of the cube is 6.93cm6.93cm6.93cm = 333cm3
By multiplying 333 by 4.50 we get the mass 1499.50g/cm3.g the molar mass of Ti (* 48g / mol), calculate the moles of Ti: 1499.75 / 48 = 31.22 moles
Multiply moles by 6.022*10*23 to calculate atoms:
If the formula is 6.02210*23 31.22molesa then a mole is equal to 1.88*10*25 atoms
Please correct me if I am wrong. [END ARTICLE]
That’s right! The formula is Ti (CO) or titanium (II) carbonyl, and the number of atoms in a mole of Ti(CO)is 6.022*10^23, not 6.93*10^23. Now you can calculate the mass of one atom: 31.22moles x 1.88*10^25 = 565g/mol for Ti (rounding to 3 significant figures). However, this is still an empirical value; we don’t yet know what the exact mass of a Ti atom is. You can also calculate that there are about 4 atoms per unit cell in your, but again that’s an average. Ti(CO)is a simple cubic structure, but crystalline Ti metal is hcp, not fcc! So you have some mismatch there. You can also calculate the mass of one atom in hcp Ti (approximate to 3 significant figures), but again this is an empirical value. I hope these calculations help you understand what atomic masses are and how they are determined!
