How many moles are in 25g of CO2?

With calculation show please

0.568 moles (3 s.f.)

Step-by-step explanation:

no. of moles= mass ÷mr

Mr (molecular mass) is the sum of atomic masses of the atoms in the compound. The atomic mass can be found from the periodic table.

Mr of CO₂

= 12 + 2(16)

= 44 amu

Thus, no. of moles

= 25 ÷44

= 0.568 moles (3 s.f.)

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
