Lena [83]3 years ago
5 0
1 mole  chromium -------------- 6.02 x 10²³ atoms
3 moles chromium ------------ ( atoms chromium )

atoms chromium = 3 x ( 6.02 x 10²³) / 1

atoms chromium = 1.806 x 10²⁴ / 1

= <span>1.806 x 10²⁴ atoms of chromium

hope this helps!</span>

In any element or substance, one mole of the substance is equivalent to 6.022 x10^23 atoms per mole. This is expressed as the Avogadro's number which is useful in finding out the total number of atoms in a sample. In this case, we are given with 3 moles of chromium. this is equivalent to 1.8066 x1024 atoms

What is the pH of 0.0001 M NaOH
kow [346]
Well. NaOH is a base. That's the first thing you need to watch for.
So to find the pOH, you take -log(.0001)
that would be 4. So now you have the pOH and <u>you still need to find the pH
</u>To find pH from pOH, you take 14(the maximum pH,sorta)-pOH(in this case 4)
14-4=10 The pH of NaOH is 10

How to calculate delta S surroundings? calculate Delta S(surr) at the indicated temperature for a reaction having each of the fo
astraxan [27]
You can use the equation ΔS(surr)=q(surr)/T or ΔS(surr)=-q(rxn)/T.
the two equations are equal since we know that the energy the system (reactoin) puts out just goes into the surroundings.  
(In other words q(surr)=-q(rxn))

Using the equation, <span>ΔS(surr)=-(-283kJ/298K)=0.9497kJ/K or 949.7J/K

This answer makes sense since the reaction is exothermic which means it released energy into the system which usually causes the entropy to increase.

I hope that helps.</span>

Calculate the number of atoms in 2 mol of sulfur dioxide (SO2).
Alex17521 [72]
Two moles of SO2 means 1.204x10^24 molecules, since there are 3 atoms in one molecule, multiply 1.204 x10^24 by 3 and you get 3.612x10^24.
