Log In Sign Up Subjects Science Chemistry Avogadro constant How many moles of atoms are in 4.63 x 10^21 Ca atoms?Question:How many moles of atoms are in 4.63 x 10^21 Ca atoms?The Mole:In chemistry, the mole is used for working with large numbers of atoms. Specifically, 1 mole ...
In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o
Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of water per mole of water. So, next we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles:...

Re: How many atoms of P are in 5 moles of P4O10? «Reply #4 on:January 02, 2011, 02:25:32 PM » So, 5 moles of P4O10 means that I have (5) * (6.023*10^23) molecules. And then I multiply that number by 4.
First,how many moles of NaOH were put into the solution?We can find this by multiplying the total volume of NaOH solution by its molarity: (0.02052 L NaOH) x (0.173 mol NaOH / 1 L NaOH) = 3.55 x 10-3mol A total of 3.55 x 10-3moles of NaOH were put into the solution.Since th...
