answer: the atomic mass of these species is different and atomic number remains same.
isotopes are the chemical species of the same element having different number of neutrons.atomic number is equal to the number of protons or electrons present in that element.
atomic number = number of electrons = number of protonsatomic mass is defined as the sum of number of protons and neutrons contained in an atom.
atomic mass = number of protons + number of neutrons
for isotopes, as the number of neutrons differ, the atomic mass also differs.
for example: carbon has 3 naturally occurring isotopes: . the atomic number remains the same but atomic mass differs.
hence, for isotopes, the atomic mass of these species is different and atomic number remains same.
answer: the partial pressure of the hydrogen gas is 93.9 kilopascals.
the partial pressure of the water vapors =
the partial pressure of the hydrogen gas =
the pressure measured in the collecting bottle =
while collecting the hydrogen gas in a collecting bottle with amount of water vapors also get introduced. the total pressure in the collecting bottle will be due to partial pressures of the water vapors and hydrogen.
the partial pressure of the hydrogen gas is 93.9 kilopascals.
all you need to do to convert is to multiply the number of kilograms by 2.2 to get the number of pounds.
76.6kg to pounds is 168.8741
