Answer:
Relative molecular of the compound or infomation like vapour density, volume occupied by a known mass of its vapour at stp, etc
Explanation:
The molecular mass of a compound is twice its vapour density. We can find the molecular formula using the relationship below:
- Empirical formula is the simplest formula of a compound. It repeats itself "n" times to become a molecular formula i.e (EF)ₙ = MF...... n is the number of times the empirical formula presents in a mole of the compound.
- Most times, n is a whole number like 1,2,3,.....

Got this off of quizlet I’m not 100% an expert but I tried to help
Answer:
As Per Given Information
Mass of Car 4000 Kg
Acceleration of car 20m/s²
we have to find the force required to make the car car accelerate at given magnitude .
Using Formulae
- Force = Mass × Acceleration
On Putting the value we obtain
↝ Force = 4000 × 20
↝ Force = 80000 N
↝ Force = 80KN
So, the force required to maintain the given acceleration is 80 KiloNewton .
