Question

How many moles of Ti are present in 5.00 moles of Ti6Al4V?

Answer 1

Answer : The number of moles of Ti present in 5.00 moles of
`Ti_6Al_4V` are 30.

Explanation : Given,

Moles of
`Ti_6Al_4V` = 5.00 moles

Now we have to determine the moles of Ti.

In
`Ti_6Al_4V`, there are 6 moles of Ti, 4 moles of Al and 1 mole of V.

As, 1 mole of
`Ti_6Al_4V` contains 6 moles of Ti

So, 5.00 mole of
`Ti_6Al_4V` contains
`5.00* 6=30` moles of Ti

Hence, the number of moles of Ti present in 5.00 moles of
`Ti_6Al_4V` are 30.

Answer 2

The given compound is:

Ti6Al4V

1 mole of Ti6Al4V contains 6 moles of Ti

therefore, 5 moles of Ti6Al4V will have: 5 * 6/1 = 30 moles of Ti

Now,

1 mole of Ti contains 6.023 * 10^23 atoms of Ti

therefore, 30 moles of Ti will be composed of: 30 *6.023 * 10^23/1

= 1.807 * 10^25 atoms

Thus, 5 moles of Ti6Al4V will have 30 moles of Ti which in turn corresponds to 1.807*10^25 atoms of Ti.
