There are 0.501 moles in 60.66g of CF2Cl2
The only stable caesium isotope is 133Cs, with 78 neutrons.
Hope this answers your Q
<span>use this formula mass = moles x molar mass</span>
Answer:
Explanation:
Hello,
In this case, since in a dilution process the moles of the solute must remain unchanged, we use the volumes and molarities as shown below:
Clearly, the concentrated solution is 12M and the diluted solution is 0.5 M, thus, the volume of the concentrated solution we should take is:
Best regards.
