Answer:
The number of molecules in the volume is molecules
Explanation:
From the question we are told that
The pressure of the ultrahigh vacuum is
The molecular diameter of the gas molecules
The temperature is
Avogadro's number is
The volume of the gas is
From the ideal gas law[] that the number of mole is mathematically represented as
Where R is the gas constant with a value
Substituting values
The number of molecules is mathematically represented as
Substituting values
molecules
Answer:
C for the first question. C for the second ( i think ) I searched the third up it should be C again ( ikr CRAZY 3 c's ) B I think for the fourth one and D for the last question.
IF ANY OF THESE ARE WRONG I DEEPLY APOLOGIZE MY HEAD IS HURTING FROM THIS ALREADY

Answer:
Acceleration = 10.06 m/s²
Explanation:
1 mile = 1.6093km
1609.3m = 1 mile
1 m = mile
50.0 miles/hour = m/s
= 22.35m/s
from equation
S = Ut + 1/2 at²
v = U + at
22.35 = 0 + a * 2.22
a = 22.35 ÷ 2.22
= 10.06 m/s²
