The gas with a higher pressure is  <u>Helium </u>

<h3 /><h3>Calculating the pressure exerted by the gases</h3>

Given that temperature and volume is held constant the pressure of a given gas can be calculated as : P = n because for a constant volume and temperature the pressure of a given gas is directly proportional to the number of moles of contained in the gas.

<u>Pressure of </u><u>Helium </u>

P = n

where n ( number of moles ) = mass of helium / molar mass

                                               = 52 / 4 = 13 moles

<u>Pressure of</u><u> Ammonia </u>

P = n

where n ( number of moles ) = mass  / molar mass of ammonia

                                                = 73 / 17.03

                                                = 4.29 moles

From the calculations above the gas with a higher pressure is Helium.

Which of the indicators on the chart above tell(s) us that Australia and New Zealand are highly developed countries?
ExtremeBDS [4]

Answer:

Answer: D

GDP per capita is a measure of a country's economic output that accounts for its number of people.

The unemployment rate is defined as the percentage of unemployed workers in the total labor force.

The infant mortality rate is the number of deaths under one year of age.

Given the above information, a country with a higher GDP would have a more stable economy aiding in growth. A lower unemployment rate would show a surplus of jobs indicating, once again, a steady and growing economy. Lastly, a lower infant mortality rate would show access to advanced medicine and a highly trained medical field. All three of these examples are indicators of a highly developed country.
