Answer:
1.8 x 10²⁴ atoms Ag
Explanation:
You can find the amount of silver (Ag) atoms by multiplying the moles by Avogadro's number. It is important to arrange the conversion in a way that allows for the cancellation of units (the desired unit should be in the numerator). The final answer should have 2 sig figs to match the sig figs of the given value.
Avogadro's Number:
6.022 x 10²³ atoms = 1 mole
3.0 moles Ag 6.022 x 10²³ atoms
---------------------- x -------------------------------- = 1.8 x 10²⁴ atoms Ag
1 mole
Answer:
146
Explanation:
uranium is 92 and the mass number of the isotope is given as a 238 therefore it is not the two protons 92 electrons and
real explanation Google it
It is C. An increase of temperature results in an increase in kinetic energy of the molecules of the substance. For example, in a gas the molecules will move about faster.
Answer:
Increased heat,increased pressure,or the use of nuclear catalyst.
