Check the circled atoms in the attached diagram

Explanation:

The circled options all belongs to the same elements. They are simply isotopes.

Since:

          Red ball = protons

          Yellow ball = neutron

           Blue ball = electron

The protons are positively charged and with the neutrally charged neutrons they both occupy the vicinity of the nucleus of an atom.

Electrons moves round the nucleus in orbits.

Atoms of the same elements have the same number of protons.

The circled options all have two protons.

The atoms only differ in the number of neutrons which signifies that they are merely isotopes.

More descriptively, the atoms are Helium atoms.

The element X has three naturally occurring isotopes. The masses (amu) and % abundances of the isotopes are given in the table b
denis-greek [22]

Answer:

220.42098 amu

Explanation:

(220 .9 X  .7422) + (220 X .0.1278) + (218.1 X 0.13) =     220.42098 amu

These are weighted averages.

So, we will take mass of one and multiply by abundance percentage that is provided and add them together.

In order to calculate the  average atomic mass, we have to convert the percentages of abundance to decimals. So, you get

(220 .9 X  .7422) + (220 X .0.1278) + (218.1 X 0.13) =     220.42098 amu

2.15 Liters of helium gas at a pressure of 58 kPa and a temperature of 25 degrees celsius, what is the new volume at stp?
Nastasia [14]
The ideal gas law is P1V1/T1 = P2V2/T2. STP means the temperature is 273 K and pressure is 101.3 kPa. According to this formula, the new volume V2=2.15*58*273/(298*101.3) = 1.13 L.
