MW of gas : 124.12 g/mol
<h3>Further explanation </h3>
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
![\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}](https://tex.z-dn.net/?f=%5Clarge%20%7B%5Cboxed%20%7B%5Cbold%20%7B%5Crho%20~%20%3D%20~%20%5Cfrac%20%7Bm%7D%20%7BV%7D%7D%7D%7D)
ρ = density
m = mass
v = volume
glass vessel wieight = 50 g
glass vessel + liquid = 148 ⇒ liquid = 148 - 50 =98 g
volume of glass vessel :
![\tt V=\dfrac{m}{\rho}=\dfrac{98}{0.989}=99.1~ml](https://tex.z-dn.net/?f=%5Ctt%20V%3D%5Cdfrac%7Bm%7D%7B%5Crho%7D%3D%5Cdfrac%7B98%7D%7B0.989%7D%3D99.1~ml)
An ideal gas :
m = 50.5 - 50 = 0.5 g
P = 760 mmHg = 1 atm
T = 300 K
![\tt PV=\dfrac{mass(m)}{MW}.RT\\\\MW=\dfrac{m.RT}{PV}\\\\Mw=\dfrac{0.5\times 0.082\times 300}{1\times 0.0991}=124.12~g/mol](https://tex.z-dn.net/?f=%5Ctt%20PV%3D%5Cdfrac%7Bmass%28m%29%7D%7BMW%7D.RT%5C%5C%5C%5CMW%3D%5Cdfrac%7Bm.RT%7D%7BPV%7D%5C%5C%5C%5CMw%3D%5Cdfrac%7B0.5%5Ctimes%200.082%5Ctimes%20300%7D%7B1%5Ctimes%200.0991%7D%3D124.12~g%2Fmol)
It has to do with the releasing of ethylene, which speeds up the ripening process
The average Kenectic energy
Answer:
d
Explanation:
because boron and fluorine are both nonmetals and don't fit the guidlelines for creating ionic compounds
A gas can move around freely while a solid is hard and can’t move around freely
