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.

A conversion factor is a fraction that is always equal to the value of 1.
Answer:
ahhhhhhhhhhhhhhhhhhhhh im not able to under stand!
Explanation:
Answer:
The first measurement is 116.84 cm, and the second measurement is 116.85 cm.
Explanation:
The problem provides both the first and second measurements so all you have to do is fill in the blank with them.
Answer:
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
Through his careful breeding of garden peas, Gregor Mendel discovered the basic principles of heredity and laid the mathematical foundation of the science of genetics.
