Let's assume that the gas has ideal gas behavior.
Ideal gas law,<span>
PV = nRT
(1)
Where, P is the pressure of the gas (Pa), V is the volume of
the gas (m³), n is the number of moles of gas (mol), R is the
universal gas constant ( 8.314 J mol</span>⁻¹ K⁻<span>¹)
and T is temperature in Kelvin.
</span>n = m/M
(2)
Where, n is number of moles, m is mass and M is
molar mass.
From (1)
and (2),
PV = (m/M) RT
By
rearranging,
M =
(mRT)/PV (3)
P = standard pressure = 1 atm = 101325
pa
V = 0.896 L = 0.896 x 10⁻³ m³
R = 8.314 J mol⁻¹ K⁻¹<span>
T = Standard temperature = 273 K
m = </span>3.87 g = 3.87 x 10⁻³ kg<span>
M = ?
</span><span>
By appying the formula,
M =(</span>3.87 x 10⁻³ kg x 8.314 J mol⁻¹ K⁻¹ x 273 K) /101325 pa x 0.896 x 10⁻³m³
<span>M = 0.0967 kg
M = 96.7 g.
Hence, the molar mass of the gas is 96.7 g.

Answer:
A binary covalent compound is composed of two different elements (usually nonmetals). For example, a molecule of chlorine trifluoride, ClF3 contains 1 atom of chlorine and 3 atoms of fluorine.
Rule 1. The element with the lower group number is written first in the name; the element with the higher group number is written second in the name. Exception: when the compound contains oxygen and a halogen, the name of the halogen is the first word in the name.
Rule 2. If both elements are in the same group, the element with the higher period number is written first in the name.
Rule 3. The second element in the name is named as if it were an anion, i.e., by adding the suffix -ide to the root of the element name (e.g., fluorine = F, "fluoride" = F-; sulfur = S, "sulfide" = S2-).
Rule 4. Greek prefixes are used to indicate the number of atoms of each element in the chemical formula for the compound. Exception: if the compound contains one atom of the element that is written first in the name, the prefix "mono-" is not used.
Explanation:
B.) it is a complete organism
Answer:
Check if the ions of two compounds exchange places.
Explanation:
The definition of single replacement is a reaction when an ion replaces another ion, thus the name.
