Chlorine-37 has an atomic mass of 36.966 amu and a percent abundance of 24.23%. To calculate the average atomic mass of chlorine, use the information in a periodic table of the element (see Resources) to find the (weighted) average but changing the percents to decimals: (34.969×0.7577)+...
You can use the atomic mass of hydrogen, measured in AMU, to calculate the fraction of a mole of the gas in your sample. Just divide the mass of your sample, in kilograms, by the mass of one mole in kilograms. Since one mole of hydrogen gas has a mass of 2.016 × 10-3 kg, ...
To calculate the molar mass,the atomic mass of each substance is multiplied with the subscript of that element in the chemical formula. Then the masses of all the elements are added. \[{{\rm{H}}_2}{\rm{O}}\] represents water. What is the value of 6.02 1023? Themoleis defined as ...
这个标准原子就是碳12原子。科学家将碳12原子的质量设定为12个原子质量单位。因此,一个原子质量单位amu,就是碳12原子质量的1/12。 Although a mass of 1 amu is nearly equal to the mass of a single proton or a single neutron, it is important to realize that the values are slightly different. Tab...
Consider the neutron, the proton, and the electron. Which has the largest relative mass? Do protons and neutrons have equal masses? What are their differences? Show how to calculate the mass of a proton, neutron, and electron in kilograms using this data: (Particle, M...
Refer to data in the table. Use the information for the isotopes of X to calculate the average atomic mass of X and identify the element. 6X: Abundance = 7.5%; Mass = 6.015 amu 7X: Abundance = 92.5%; Mass = 7.016 amu If isotope 1 ...
Take mass of proton (mp)=1.007825 amu, mass of a neutron (mn)=1.008665 amu and 1amu=931.5 MeV View Solution The sun is believed to be getting its energy form the fusion of four protons to form a helium nucleus and a pair of positrons. Calculate the release of energy per fusion in ...
What is the difference between isotope abundance and isotope mass? How do you calculate the atomic number of isotopes? What is relative abundance of isotopes? How is the atomic mass of an element calculated? How to find the amu of an isotope? How to find the number of neutrons in an isot...
