Where are the units for 0.25 ,0.15 and 0.4?

If a mixture of nitrogen, oxygen, and helium contains 0.25, 0.15 and 0.4 respectively,
and the partial pressure of oxygen is 2.5 atmosphere,
then the partial pressure of helium is {rounded to a reasonable number of significant digits).

If the mixture of nitrogen, oxygen, and helium contains 0.25, 0.15 and 0.4 respectively,
the answer is too.

If the mixture of nitrogen, oxygen, and helium contains 0.25, 0.15 and 0.4 respectively,
then the number of moles is
for oxygen, and
for helium,
and the partial pressure of helium is
