125 lbs. = 3.414e+28 amu
There are various isotopes of tin with different atomic mass. The average atomic mass of tin is 118.71 amu. The symbol commonly used for tin is Sn.
If you weigh 115 pounds on earth, your mass is 52.2 kilograms. If you weigh 125 pounds on the moon, your mass is 319.5 kilograms.
Astatine-210 (At-210) has a mass number of 210. Since Astatine has an atomic number of 85, which indicates the number of protons, you can calculate the number of neutrons by subtracting the atomic number from the mass number: 210 - 85 = 125. Therefore, Astatine-210 has 125 neutrons.
125 pounds is approximately equal to 56.7 kilograms.
Atomic mass
Protons = Atomic Number = 50 Neutrons = Atomic Mass - Atomic Number = 125 - 50 = 75
The element with atomic number 50 is tin (Sn). The mass number of 125 indicates that this particular isotope of tin contains 75 neutrons (mass number - atomic number).
There are various isotopes of tin with different atomic mass. The average atomic mass of tin is 118.71 amu. The symbol commonly used for tin is Sn.
Look on the periodic table for the element with the closest atomic mass to that number. It's lead (Pb, #82.) Now, for the neutron count, you round that atomic mass to the nearest whole number, which is 207, then subtract the atomic number of 82 from it. 207-82=125. So 125 neutrons.
If you weigh 115 pounds on earth, your mass is 52.2 kilograms. If you weigh 125 pounds on the moon, your mass is 319.5 kilograms.
If ounce-mole - in ounces if pound-mole - in pounds and so on
125 pounds is equal to approximately 56,699 grams.
The answer is 56.699 kg (approx.). Kilogram is the SI unit of mass and pound is an imperial unit of mass. To convert from pound to kg, multiply the pound unit by 0.453592.
125 pounds of cement weighs 125 pounds.
If its a neutral atom, there will be the same number of protons as electrons. The atomic number will tell you how many protons there are, so there are 50 protons and 50 electrons.The mass number is the sum of the number of protons (or electrons in a neutral atom) and the number of neutrons. Since we know there are 50 protons, we subtract 125 with 50 to get 75 neutrons.
To determine the number of neutrons, subtract the atomic number from the mass number. In this case, 208 - 83 = 125 neutrons.
It is equal to 275577.82 pounds approximately. Kilogram is the metric unit and pound is the imperial unit for mass. 1 Kilogram is 2.204 pounds. So we multiply kg by 2.204 to get the equivalent pounds.
