You can't calculate the electronegativity difference of a single molecule you'll need a frame of reference to explain the electronegativity difference and properties arising due to the difference. Another term arise here is modified electronegativity that is calculated within the molecule between two atoms of different electronegativity and use to explain the nature of molecule wether they are electron withdrawing group or electron donating group and also used to compare the electronegativity with other molecule!
V = 550 mL = 0.550 L
V = 22.4 L/mol (STP)
M(CO₂)=44.01 g/mol
n(CO₂)=v/V
m(CO₂)=n(CO₂)M(CO₂)=vM(CO₂)/V
m(CO₂)=0.550*44.01/22.4=1.08 g

Answer:
The acceleration of ball is 18 m/s².
Explanation:
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
Given data:
Mass of ball = 0.60 kg
Force on it = 10.8 N
Acceleration = ?
Solution:
a = 10.8 N/0.60 kg
a = 18 N/kg
N = kg.m/s²
a = 18 kg.m/s² / kg
a = 18 m/s²
