How do I create a web page that lets a user enter as many values as they wish until the entry of a 0. Then find the sum and the average of all the numbers and show sum and average on screen. In code?
You could do this using Javascript.1) create a textfield2) create a submit button3) define two Javascript variables: a running tally, and a click-counter4) give the button an onclick event that calls a function that works like this:read the value from the text fieldconvert it to a numeric valueif that value is 0 {if the counter != 0 {display the tally and the average (which equals tally over counter)}else{either display an error message, or 0 as both the tally and average - to your taste.}reset both the tally and the counter to 0}else{add the value to the tallyincrement the counter by 1}And here's a working example of how to do it:span.buttonClass{background-color: #C8C8C8;padding: 4px;border-width: 2px;border-style: outset;font-weight: bold;}The Summinator!var tally = 0, counter = 0;function addValue(){var textfield = document.getElementById("addVal");var avgfield = document.getElementById("avgfield");var sumfield = document.getElementById("sumfield");var num = parseFloat(textfield.value);var sum, avg;textfield.value = '';if(isNaN(num)){ // make sure they entered a numberalert("Please enter a numeric value.");}else{if(num != 0){tally += num;counter ++;sumfield.textContent = "";avgfield.textContent = "";}else{if(counter == 0){sum = avg = 0;}else{sum = tally;avg = tally / counter;}sumfield.innerHTML = "The sum is " + sum;avgfield.innerHTML = "The average is " + avg;tally = counter = 0;}}}Add ValueYou can even make it a little nicer by having it output the sum and average each time a number is entered, rather than waiting for the zero input (which would still reset things). That actually simplifies the code too, and would look like this:...if(isNaN(num)){ // make sure they entered a numberalert("Please enter a numeric value.");}else{if(num != 0){tally += num;counter ++;sum = tally;avg = tally / counter;}else{sum = avg = tally = counter = 0;}sumfield.innerHTML = "The sum is " + sum;avgfield.innerHTML = "The average is " + avg;}...

What is the natural abundance of Br-81?
The natural abundance of Br-81 is approximately 49.31%.
Is the isotope 79-Br or 81-Br more common and why?
The isotope 79-Br is more common than 81-Br because it is the most stable isotope of bromine. 79-Br has a higher abundance in nature because it has a longer half-life compared to 81-Br, which is less stable and less abundant.
Which of the following is the correct nuclide symbol for bromine-81?
The correct nuclide symbol for bromine-81 is ^(81)Br.
What is the most common isotope Br?
The most common isotope of bromine is bromine-79 (Br-79), which makes up about 51% of naturally occurring bromine.
If the mass of Br-81 is 80.9163 amu what is the mass of Br 79 I know the answer is 78.9183 but how does one find the answer?
To find the mass of Br-79, you subtract the difference in mass between Br-81 and Br-79 from the mass of Br-81. Mass of Br-81 = 80.9163 amu Mass of Br-79 = Mass of Br-81 - (Mass of Br-81 - Mass of Br-79) = 80.9163 - (80.9163 - 78.9183) = 78.9183 amu

How many peaks will be present in a mass spectrum for?
The number of peaks in a mass spectrum depends on the complexity of the molecule being analyzed. A simple molecule may have one or a few peaks corresponding to different fragments formed during ionization, while a more complex molecule can produce multiple peaks due to different fragmentation patterns.
