Chapter E, Problem 1E
What are the standard SI base units of length, mass, time, and temperature?
Expert Solution & Answer
Interpretation Introduction
To determine:
The standard SI base units of length, mass, time, and temperature.
Answer to Problem 1E
Solution:
Length = meter (m)
Mass = kilogram (kg)
Time = second (s)
Temperature = Kelvin (K)
Explanation of Solution
SI stands for Systéme International; which is an international system for units. It is used to ensure measurements and units in various system. As the name implies, it also standardizes unit systems.
There are many types of dimensions which can be measured, the most commons are length, mass, time and temperature.
Each dimension should have a standard SI value, that is, it will not change, will be considered the basis of the system.
Conclusion
SI Standard units are required to have a system in which dimensions are standardized within their units/measurements. The units for length, mass, time and temperature are meter, kilogram, second and kelvin, respectively.

A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of
hydrocyanic acid is 9.21.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.
