Answer:
Likely
(indium.)
Explanation:
Number of atoms:
.
Dividing,
, the number of atoms by the Avogadro constant,
, would give the number of moles of atoms in this sample:
.
The mass of that many atom is
. Estimate the average mass of one mole of atoms in this sample:
.
The average mass of one mole of atoms of an element (
in this example) is numerically equal to the average atomic mass of that element. Refer to a modern periodic table and look for the element with average atomic mass
. Indium,
, is the closest match.
Answer:
<h2>94.87 mL</h2>
Explanation:
The new volume can be found by using the formula for Boyle's law which is

Since we're finding the new volume

We have

We have the final answer as
<h3>94.87 mL</h3>
Hope this helps you
I think the the state <span>of the air in an isolated room is completely specified by the temperature and the pressure. Since it is isolated, the volume would be the same as the room. Gas is specified by temperature, pressure and volume. Having the values for pressure and temperature then the gas is completely specified. Hope this answers the question.</span>
