Percent abundance can be calculated by finding the percentage of an isotope compared to another isotope of an element using its relative atomic mass. This is an algebraic process and depends upon several measurements.Know More
Because there are various isotopes of an element, its atomic weight is a calculation of the atomic masses and relative abundances of each isotope of that element. Using algebra, the atomic weights and respective relative abundance percentages of each isotope are multiplied and then added together to find the atomic weight of the element in question.
To accurately measure the atomic mass of an element, a mass spectrometer is used. In this instrument, atoms are positively ionized, accelerated and then deflected by a magnetic field. The amount of deflection is partially determined by the element's atomic mass.Learn more about Math Calculators
The center of gravity is calculated using two equations, the x coordinate is calculated by x = sum of (mi * xi) / sum of mi. The y coordinate is calculated as y = sum of (mi * yi) / sum of mi. Sometimes the z coordinate is also calculated.Full Answer >
Jari Jokinen's and the Math Easy Solutions percentage calculators both allow a user to find percentages by entering values into common percentage verbiage used in word problems. The Math Is Fun percentage calculator allows someone to compare two numbers percentage-wise.Full Answer >
When purifying a substance in chemistry, use (collected mass/starting mass)*100 to calculate percent recovery. This formula is also commonly stated as (pure product recovered/crude material used)*100.Full Answer >
A $15 shirt would cost $12 if it were 20 percent off. The 20 percent discount would come to $3, and subtracting $3 from $15 gives $12.Full Answer >
