Question

Solve for x, where M is molar and s is seconds.

x=(2.4×103M−2s−1)(0.38M)3

Answer 1

x = 131.69Ms⁻¹

Step-by-step explanation:

x = (2.4×10³M⁻²s⁻¹) (0.38M)³

Upon expanding, we have;

x = (2.4 × 10³M⁻²s⁻¹) (0.38M) * (0.38M) * (0.38M)

x = (2.4 × 10³M⁻²s⁻¹) (0.054872 M³)

x = 2.4 * 0.054872 * 10³ * M⁻²s⁻¹ * M³

x = 0.13169 * 10³ * M⁻²s⁻¹ * M³

x = 131.69 * M⁽⁻²⁺³ ⁾* s⁻¹

x = 131.69 * Ms⁻¹

x = 131.69Ms⁻¹

Answer 2

x = 130 Ms⁻¹

Step-by-step explanation:

The equation is:

x = (2.4 x 10³ M⁻²s⁻¹)(0.38 M)³

The expression raised to the power of 3 is simplified:

x = (2.4 x 10³ M⁻²s⁻¹)(0.054872 M³)

The two values are multiplied together and units canceled:

x = 130 Ms⁻¹
