Fundamental E.1

Postby WCano_4B » Fri Oct 04, 2019 1:03 pm

How do I cross cancel the given 1.0 mol Ag atoms? I know that I have Avogadro’s number over 1.0 mol Ag but do not know how to cancel the bottom portion to continue.

You have to multiply Avogadro's number with the diameter of the atoms which would be ( two times 144pm= 288pm) and also convert the diameter to meters by multiplying it by (10 to the power of negative 12). Once you multiply these three figures, you should get the answer.

and then don't forget to convert your final units in meters not just pm, making it 1.73 x 10^14 m

How would you convert pm to m?

pm is picometers, and 1 pm = 10^-12 m. So, 1.73*10^26 pm (10^-12 m/ 1 pm) = 1.73 * 10^14 m
