What are some common isotopes of mercury?

The three most stable isotopes of hydrogen: protium (A = 1), deuterium (A = 2), and tritium (A = 3).

Protium, the most common isotope of hydrogen, consists of one proton and one electron. ...

A deuterium atom contains one proton, one neutron, and one electron.

Explanation:

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
