Answer:
"mole"
Explanation:
That is the definition of mole. Mole is a unit for the measurement of how much there is of something. In other words, in SI, 1 mol of a substance contains the same number of molecules/atoms as in 12 grams of carbon 12.
(Approximately 6.28 × 10^23 --> Avogadro's constant)

New analysis through 2014 shows that temperature is once again rising at about the same pace as it did over the second half of the 20 th century. PRESS RELEASE. Using the data that were available at the time (through 2012), the last climate report from the Intergovernmental Panel on Climate Change concluded that there had been no statistically significant increase in global surface temperature

For this item, we need to assume that air behaves like that of an ideal gas. Ideal gases follow the ideal gas law which can be written as follow,
PV = nRT
where P is the pressure,
V is the volume,
n is the number of mols,
R is the universal gas constant, and
T is temperature
In this item, we are to determine first the number of moles, n. We derive the equation,
n = PV /RT
Substitute the given values,
n = (1 atm)(5 x 10³ L) / (0.0821 L.atm/mol.K)(0 + 273.15)
n = 223.08 mols
From the given molar mass, we calculate for the mass of air.
m = (223.08 mols)(28.98 g/mol) = 6464.9 g
<em>ANSWER: 6464.9 g</em>
It would most likely be a molecular compound. A molecular compound contains two or more nonmetals.
Answer:
is a chemical bond i think is true
