Answer:
Explanation:
1 mol of anything is 6.02 * 10^23 atoms (in this case)
x mol of 3.01 * 10^22
Set up the proportion
1/x = 6.02*10^23 / 3.01 * 10^22 Cross multiply
x*6.02 * 10^23 = 1 * 3.01 * 10^22 Divide by 6.02*10^23
x = 3.01 * 10^22 / 6.02*10^23
x = 1/(2 * 10)
x = 1/20 mol
x = 0.05 mol
Answer:
A team of Chinese researchers have turned cheap copper into a new material “almost identical” to gold, according to a study published in peer-reviewed journal Science Advances on Saturday. The fast-moving ionized particles blasted copper atoms off the target.
hope this helps
have a good day :)
Explanation:
B. compound
source is Glencoe Science book grade 7.
Also I just happening to be learning about this at school
The answer is volume that is volume limits the precision of data obtained in an experiment .
As while pouring of the liquids, we control the volume, but it can have been off. And this could results in the wrong mole to mole ratio.Thus it limits the precision, So the answer is that volume limits the precision of data obtained in an experiment .

See explanation
Explanation:
According to Louis de Broglie, particles could exhibit wavelike properties and have an associated wavelength.
Now for a turtle with a mass of 450. g, 29. cm long, moving at 2.7 cm/s, recall that we can only describe a by quantum mechanics when the body is very small and its associated wavelength is large.
This object has a large mass, hence it is discussed by classical rather than quantum mechanics
