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;}...
the number zero is first used by Indians only not by any one else<br /><br /><br /><br /> The number zero was actually invented by the <i><b>Ancient Egyptians
It is 81*81*81. Which is 531,441.
Br means Mist... in spanish i guess Br comes from Bruma, a kind of Mist. Fg is Fog, Fu is Smoke (from "fumarola" in spanish as well)
79-Br is more common because its abudance is 50.69%. 81-Br's abudance is 49.31% making it less common. Abudance is the rate at which the isotope is found in nature. In this case out of every 100 Bromine atoms you found 51 would be 79-Br and 41 would be 81-Br.
It may be Bromine-79 (79Br) because it is one of the 2 stable isotopes. The other one is Bromine-81 (81Br).
the abundance is 50%.
There will be four peaks in the mass spectrum.
Br-80 has 35 protons.
Bromine-79 has 44 neutrons and bromine-81 has 46 neutrons. All the isotopes of bromine has 35 protons.
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
