4 because he needed to see
Answer:
The answer for this selection is 4
Explanation:
Answer is (1) - less mass and greater penetrating power.
Alpha particle is a ₂⁴He nucleus while beta particles are electrons. Hence, the mass of alpha particle is greater than the mass of beta particle. But, the penetrating power is higher in beta particle than alpha particle. Alpha particles can be blocked by few papers but beta particles can go through those papers.
You need to start by subbing in the correct numbers for these values/properties in this formula:
number of moles (mol) = molar concentration (mol/L) x volume (L)
