guajiro [1.7K]

Answer:

1.18 moles of gas

Explanation:

3.00 moles of gas are pumped into a 1.00L rigid container with a pressure of 1.98 atm. The gas is released from the container until the pressure is 0.78 atm, how many moles of gas remain in the container?​

for the sealed rigid container, the pressure is directly proportional to the amount of gas

3.00moles/1.98  atm =  ? moles/0.78 atm

? = 3.00 X 0.78/1.98  =1.18 moles of gas

How is Oxygen -18 different from oxygen -16?
Oksanka [162]

A  O-18 has 2 more neutrons than O-16

<h3>Further explanation</h3>

Oxygen is located in group 16 in the p block which has the atomic number 8

In the atomic symbol (neutral), the atomic number indicates the number of electrons and protons. while the number of neutrons is obtained from the difference between the mass number and the atomic number.

The isotope will have the same number of protons (atomic number) but a different mass number

Isotopes of oxygen include: O-18 and O-16

\tt _8^{18}O~\rightarrow neutron=18-8=10,proton=8\\\\_8^{16}O\rightarrow neutron=16-8=8,proton=8
