What is the mass of lead?
Lead (Pb) has the atomic number 82 with an Atomic Mass of 207.2 amu.
Is atomic masses measured in amus?
Yes, atomic masses are typically measured in atomic mass units (amu), which are defined as one twelfth of the mass of an atom of carbon-12. This unit is convenient for expressing the masses of atoms because it allows for a more manageable scale of values compared to using the actual mass in kilograms or grams.
How many atomic mass units does an electron have?
An electron has a mass of about 0.00054858 atomic mass units (amu) or approximately 1/1836 of a proton or neutron.
How many grams are there in one atomic mass unit of a material?
I have been studying this in science class. The answer to your question has more than one. If the atomic mass unit is 1 gram of hydrogen, the number of atoms would be about 15 to 22. If there is more than 1 gram of hydrogen, the answer will vary.
How do the isotopes deuterium and tritium different?
All hydrogen atoms of any kind have one proton in the nucleus. The number of neutrons differ for the 3 isotopes.Regular hydrogen has no neutrons in the nucleus (1H), deuterium has one neutron (2H), and tritium has two neutrons (3H).
How tall is Amus Osaurus?
Amus Osaurus is 5' 6 1/2".
Is chlorine a element or compound or a mixture?
Chlorine is an element on the periodic table. If you look, its average atomic mass is 35.5 amus. It would be a compound if it was 'connected' with another element, ie Hydrogen. HCl is considered a compound, but chlorine (Cl) alone is just an element.
What has the author Se amus Mac Conmara written?
Se amus Mac Conmara has written: 'Saol agus saothar She amais Mhic Chonmara'
What episode does ikuto sleep in amus room?
65 and a bunch of others
What is vanadium's atomic radii?
vanadiums atomic weight is 50 AMUs
True or false relative atomic masses sre measured in amus?
true
What is the mass of lead?
Lead (Pb) has the atomic number 82 with an Atomic Mass of 207.2 amu.
What element is 40 amu?
The element with an approximate atomic mass of 40 amu is Calcium (Ca).
Is atomic masses measured in amus?
Yes, atomic masses are typically measured in atomic mass units (amu), which are defined as one twelfth of the mass of an atom of carbon-12. This unit is convenient for expressing the masses of atoms because it allows for a more manageable scale of values compared to using the actual mass in kilograms or grams.
What is the mass in amus of a neutral atom with 53 protons and 74 neutrons?
The stable isotope of iodine, 127I, with athe atomic mass 126,904 473(4).
How many atomic mass units does an electron have?
An electron has a mass of about 0.00054858 atomic mass units (amu) or approximately 1/1836 of a proton or neutron.
What is the osmolarity of 10.00 grams of aluminum sulfate dissolved in 200ml of aqueous solution?
To find this answer it is necessary to first find the chemical formula of aluminum sulfate utilizing the valence charges from the periodic table. Aluminum Sulfate is a molecular formed by the ionic bonding of aluminum to to the polyatomic ion of sulfate Al = +3 SO4 is a polyatomic ion with a charge of -2 Therefore after balancing the equation, you get the chemical formula Al2(SO4)3 Next, in order to find osmolarity, you must first find molarity. This is done by converting grams to moles. Moles are calculated in grams/Liter and is equal to the molecular weight. What is the molecular weight of aluminum sulfate. Looking at the periodic table, you sum the atomic weights of each element, shown in AMUs. Al = 27 (x2) = 54 S = 32 (x3) =96 O = 16 (x12) = 192 We add these up to determine the molecular weight of the substance, which can be used to determine the molarity of this solution. MW = 342g, which means that one mole of aluminum sulfate is 342 grams per liter of water. We can now use the information presented in the above problem to determine molarity 10 grams dissolved in 200 ml of water. Since measurements are in grams per liter, we can assume that if 10 grams were dissolved in 200 ml of water, then 50 grams will dissolve in 1000 ml, or 50 grams per liter (multiply both factors by five). We must use our grams of solute to convert grams into our molarity 50 g x 1 mole/342 grams of aluminum sulfate to determine the molarity. = .15 M At this point, to determine osmolarity, you must be aware that osmolarity is the measure of PARTICLES within a solution per liter. Realizing that aluminum sulfate is held together by an ionic bond, it will freely dissolve in water and produce Al ions and SO4 ions. So we sum the particles of each: 2 Al ions per molecule 3 SO4 ions per molecule Therefore, multiplying the molarity of the aluminum sulfate solution times 5 (total 5 particles from each molecule) will give you the osmolarity. = 0.73 Osm per liter of aqueous solution.
