Answer:
a = 68 m/s²
Explanation:
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Vf - Vi/t
a = acceleration
Vf = final velocity
Vi = initial velocity
t = time
Units:
The unit of acceleration is m.s⁻².
Given data:
a = Vf - Vi/t
a = 1700 m/s - 0 m/s / 25 sec
a = 1700 m/s / 25 sec
a = 68 m/s²
CH3 is the empirical formula for the compound.
A sample of a compound is determined to have 1.17g of Carbon and 0.287 g of hydrogen.
The number of atom or moles in the compound is
1.17 g C X 1 mol of C / 12.011 g C = 0.097411 mol of C.
0.287 g H x 1 mol of H / 1 g H = 0.28474 mol H.
This compound contains 0.097411 mol of carbon and 0.28474 mol of Hydrogen.
So we can represent the compound with the formula C0.974H0.284.
Subscripts in formulas can be made into whole numbers by multiplying the smaller subscript by the larger subscript.
we can divide 0.284 by 0.0974.
0.284 / 0.0974 = 3.
So here, Carbon is one and hydrogen is 3.
We can write the above formula as a CH3.
Hence the empirical formula for the sample compound is CH3.
