Answer:
element
A pure substance is matter that is uniform throughout and has consistent properties. All matter is made up of very small particles called atoms. Atoms are the building blocks of all matter. When a substance contains only one type of atom, it is called an element.

Total we want 48 titanium to make 12.0moles
The atoms C,H,O and N becomes more electronegative as the periodic table's right side and top get increasingly electronegative as you move down it. A hydrogen bond needs to share elements with hydrogen in order to exist.
As you move up and to the right of the periodic table, the electronegative properties increase. To form a hydrogen bond, elements would have to be shared with hydrogen. Each element becomes increasingly electronegative as you move further right on the periodic table, with the exception of noble gases (which aren't particularly reactive).
In order to obtain stability, atoms C, H, O, and N would therefore most likely desire to share their electrons (i.e., they are more electronegative because they wish to "hog" electrons). Due to its intermediate electronegativity, hydrogen has a mid-range potential for forming bonds with other molecules.

is this a multiple choice question?
744 atomic mass units (a.m.u)
Explanation:
We know that 1 carbon atoms weighs 12 atomic mass units (a.m.u). Knowing this we devise the following reasoning:
if 1 carbon atom have a mass of 12 atomic mass units (a.m.u)
then 62 carbon atoms have a mass of X atomic mass units (a.m.u)
X = (62 × 12) / 1 = 744 atomic mass units (a.m.u)
