Given:
No of atoms present= 8.022 x 10^23 atoms
Now we know that 1 mole= 6.022 x 10^23 atoms
Hence number of moles present in 8.022 x 10^23 atoms is calculated as below.
Number of moles
= 8.022 x 10^23/6.022x 10^23
=1.3 moles.
Hence we have 1.3 moles present.
This is a tough one but the answer is water
think of it this way the ocean is water
Answer:
Heating this gas to 55 °C will raise its volume to 6.87 liters.
Assumption: this gas is ideal.
Explanation:
By Charles's Law, under constant pressure the volume 
of an ideal gas is proportional to its absolute temperature 
(the one in degrees Kelvins.)
Alternatively, consider the ideal gas law:
.
is the number of moles of particles in this gas. should be constant as long as the container does not leak.
is the ideal gas constant. 
is the pressure on the gas. The question states that the pressure on this gas is constant.
Therefore the volume of the gas is proportional to its absolute temperature.
Either way,
.
.
For the gas in this question:
- Initial volume:
.
Convert the two temperatures to degrees Kelvins:
- Initial temperature:
. - Final temperature:
.
Apply Charles's Law:
.
Isotopes of any given factor all incorporate the equal variety of protons, so they have the identical atomic wide variety (for example, the atomic wide variety of helium is usually 2). Isotopes of a given factor include exceptional numbers of neutrons, therefore, special isotopes have special mass numbers.
