How many moles of atoms are in 12.0 gram of helium?
For this you need the atomic mass of Hg. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. 12.0 moles Hg × 200.6 grams = .0598 grams Hg
What is the atomic mass of hg?
Mercury is a metal element. Atomic mass of it is 200.
What is the mass of mercury Hg?
The atomic mass is 201 (rounded to whole numbers). Is that what you needed?
What element has a mass number of 122 and 72 neutrons?
Mercury (Hg) has an average atomic mass of 200.59. This is an average based on the percentages of the naturally occurring isotopes of Mercury. There is an isotope of Mercury that has 201 particles in the nucleus. Since Mercury's atomic number is 80, Mercury-201 has 80 protons and 121 neutrons in its nucleus.
What is the percentage of mercury (by mass) in the 4.75 g of dimethylmercury?
Dimethylmercury = (CH3)2Hg and molar mass = 230.7 g/moleatomic mass Hg = 200.6Percent Hg by mass = 200.6/230.7 (x100) = 87.0 %.This is the percent in 4.75 g or 47.5 g or in 475 g. It won't change. If you need the mass of mercury in 4.75 g of diemthyl mercury, then it will be 4.75 g x 0.87 = 4.13 g4.13 g/4.75 g (x100) = 87% Hg
What does Hg stand for in chemistry?
Hg stands for mercury metal..only liquid state meta
How do you Convert 8.50 grams HgNO32 to moles?
For this you need the atomic (molecular) mass of Hg(NO3)2. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. Hg(NO3)2=324.6 grams8.50 grams Hg(NO3)2 / (324.6 grams) = .0262 moles Hg(NO3)2
How many moles of atoms are in 12.0 gram of helium?
For this you need the atomic mass of Hg. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. 12.0 moles Hg × 200.6 grams = .0598 grams Hg
What is the symbol and the number of mercury?
We use Hg as the symbol. Atomic number of Hg is 80.
What element has a mass number of 176?
Mass number is the number of nucleons, (protons and neutrons) in the nucleus. The isotope mercury-200 is stable and accounts for around 23% of naturally occurring mercury. The nearby elemnts thallium and gold do not have a stable isotope with mass number 200
What number is mercury in the periodic table of the elements?
its symbol is Hg its atomic number is 80 its atomic mass is 200.59 its a transition metal and its appearance is a silvery color
Which element has an atomic mass of about 200.54?
Mercury (Hg) has an atomic mass of 200.59
What will be the no of neutrons protons of hg having mass no 200 atomic no 80?
The number of protons = the atomic number. The number of neutrons = the mass number - the atomic number Protons = 80 Neutrons = 120 Also, for extra information, not that you need it, the element would be mercury.
What is the atomic mass of hg?
Mercury is a metal element. Atomic mass of it is 200.
What is the mass of mercury Hg?
The atomic mass is 201 (rounded to whole numbers). Is that what you needed?
What is a atomic mass for?
the Atomic Mass is how much an element weighs
The chemical symbol for element Mercury is?
Hg is the chemical symbol for mercury
