To solve for x, we will substitute the given values into the equation and perform the calculations:
x = (4.3 × 10^3 M^−2 s^−1) (0.45M)^3
First, let's simplify the expression (0.45M)^3:
(0.45M)^3 = (0.45)^3 * M^3
= 0.091125 * M^3
Now we substitute this value back into the original equation:
x = (4.3 × 10^3 M^−2 s^−1) * (0.091125 * M^3)
Next, we simplify the expression (4.3 × 10^3 M^−2 s^−1) * (0.091125 * M^3):
x = (4.3 × 10^3) * (0.091125) * M^(-2 + 3) * s^(-1)
= (4.3 × 10^3) * (0.091125) * M^1 * s^(-1)
= 391.875 * M * s^(-1)
Thus, the simplified expression for x is:
x = 391.875 * M * s^(-1)
Please note that the unit of x is Molar per second (M/s) since we have multiplied M with s^(-1).
