The complete question is as follows: How many moles of a gas at 100 c does it take to fill a 1.00 l flask to a pressure of 152kPa
Answer: There are 0.0489 moles of a gas at
is required to fill a 1.00 l flask to a pressure of 152kPa.
Explanation:
Given: Volume = 1.00 L,
Pressure = 152 kPa (1 kPa = 1000 Pa) = 152000 Pa
Convert Pa into atm as follows.

Temperature = 
Using the ideal gas formula as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.

Thus, we can conclude that there are 0.0489 moles of a gas at
is required to fill a 1.00 l flask to a pressure of 152kPa.

Answer:
Approximately
.
Explanation:
Lookup Avogadro's Number:
(three significant figures.)
Lookup the relative atomic mass of
,
, and
on a modern periodic table:
(For example, the relative atomic mass of
is
means that the mass of one mole of
atoms would be approximately
grams on average.)
The question counted the number of
molecules without using any unit. Avogadro's Number
helps convert the unit of that count to moles.
Each mole of
molecules includes exactly
of these
molecules.
molecules would correspond to
of such molecules.
(Keep more significant figures than required during intermediary steps.)
The formula mass of
gives the mass of each mole of
molecules. The value of the formula mass could be calculated using the relative atomic mass of each element:
.
Calculate the mass of approximately
of
:
.
(Rounded to three significant figures.)
Answer:
True
Explanation:
The more of each substanse that you add to the bag will cause it to produce faster and more gas.
Answer:
it is technically biological weathering but mechanical works as well
