How many element combos are there?
The total number of element combinations depends on the number of elements that are being combined. For example, if you are combining 2 elements, there would be a total of 2 combinations (element 1 + element 2). If you are combining 3 elements, there would be a total of 6 combinations (element 1 + element 2, element 1 + element 3, element 2 + element 3). The formula to calculate the number of combinations is n(n-1)/2, where n is the number of elements being combined.
What data must you know about the the isotopes of an element to calculate the atomic mass of an element?
Number of protons
What is necessary to calculate the atomic mass of an element is?
You need to know the atomic # or the masses of each isotope of the element.
How long does it take to heat 450 liters water with 20killowatt element?
To calculate the time it takes to heat 450 liters of water with a 20-kilowatt element, you need to consider the heat capacity of water (4.18 J/g°C), the starting temperature of the water, and the desired ending temperature. With this information, you can calculate the total energy needed to heat the water and then divide it by the power of the element (20,000 watts) to find the time.
How do you calculate from the periodic table the density of an element?
To calculate the density of an element from the periodic table, you would need to know the element's atomic mass and atomic volume. The formula for density is mass divided by volume. You can find the atomic mass on the periodic table and calculate the volume using the element's atomic radius or other relevant data.
How do you calculate the percent by mass of an element in a compound?
To calculate the percent by mass of an element in a compound, you divide the mass of the element by the total mass of the compound and then multiply by 100. This gives you the percentage of the compound's mass that is made up of that specific element.
How do you calculate the Percent composition by mass of chloroform?
To calculate the percent composition by mass of chloroform (CHCl3), find the molar mass of each element (carbon, hydrogen, and chlorine) and the total molar mass of chloroform. Then, divide the molar mass of each element by the total molar mass and multiply by 100 to get the percentage of each element in chloroform.
Write an awk program to search an element from an array?
Actually, if you use the awk language with associative arrays there is no need to search for an element of an array:val["abc"] = 2 ;will set the element 'abc' in the list 'val' to a value of 2. Since all values start out as blank or 0, finding if an element has a value is easy:if (val['abc'] == 2){# found the value}

The formula to calculate the number of combinations is n(n-1)/2, where n is the number of elements being combined.
How is the percent composition by mass determined?
The percent composition by mass of a compound is determined by dividing the mass of each element in the compound by the total mass of the compound, then multiplying by 100 to get the percentage. This calculation gives the proportion of each element in the compound by mass.
How do you calculate the relative atomic mass of an element?
To calculate the relative atomic mass of an element, you multiply the mass of each isotope of the element by its natural abundance, then add these values together.
How do you calculate the grams of an element in a specific amount of a compound?
To calculate the grams of an element in a compound, you need to find the molar mass of the element and the compound. Then, use the formula: (mass of element/molar mass of compound) x molar mass of element. This will give you the grams of the element in the compound.

How do you calculate the atomic mass of an element?
To calculate the atomic mass of an element, you multiply the mass of each isotope by its relative abundance, then add the results together.
What is the percent of a composition of a compound containing 8.6g of Be and 52.4g of I?
To find the percent composition of each element in the compound, you first calculate the molar mass of Be (9.01 g/mol) and I (126.90 g/mol). Then, calculate the percent composition of each element by dividing the mass of the element by the total molar mass of the compound and multiplying by 100. The percent composition of Be is 5.14% and the percent composition of I is 94.86%.
How is the atomic mass of an element calculate?
By taking the wieghted averages of naturally occurring isotopes of that element. :)
