A 0.928 g cereal sample was digested in acid and diluted to a final volume of 20.0 mL. It was then subjected to a further 10-fold dilution. When that solution was evaluated using ICP-MS, a particular element was present at 258.9 ppb (wg/L). How many milligrams of the element were present in the cereal sample? Enter the numerical value as a number ( 0.0315 mg as 0.0315). Note: The question is asking for milligrams in the sample not milligrams element...

Lab Topics • The basics of Array object Use the following Coding Guidelines • When declaring a variable, you usually want to initialize it. Remember you cannot initialize a number with a string. Remember variable names are case sensitive. Use tabs or spaces to indent code within blocks (code surrounded by braces). Use white space to make your program more readable. Use comments after the ending brace of classes, methods, and blocks to identify to which block it belongs. Problem...

The following C++ code has a problem where the loop can exceed the size of the array if the user inputs too many numbers. #include <iostream> using namespace std; int main() { int nums[20] = { 0 }; int a[10] = { 0 }; cout << a << endl; cout << nums << endl; cout << "How many numbers? (max of 10)" << endl; cin >> nums[0]; for (int i = 0; i < nums[0]; i++) { cout << "Enter...

A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...

JAVA PROGRAMMING PLEASE This lab has three parts: Create an ArrayList class. Create a LinkedList class. Print out the results after testing each of the methods in both of the classes and solving a simple problem with them. Task 1 – ArrayList Class Create an ArrayList class. This is a class that uses an internal array, but manipulates the array so that the array can be dynamically changed. This class should contain a default and overloaded constructor, where the default...
Billy’s Fizzy Flavours Inc. wants to estimate the average volume per can of Crazy 88 Cola with 90% confidence.
QUESTION 2. Billy’s Fizzy Flavours Inc. wants to estimate the average volume per can of Crazy 88 Cola
with 90% confidence.
(a) In practice, the soft drink producer does not know the population mean or population standard deviation
of the volume per can. However, for the purpose of this question we will assume the volume per can is
normally distributed with a mean of 353 mL and a standard deviation of 2 mL. Use this information and the
Excel procedure...
