What is the atomic mass of hg?
The atomic mass of mercury (Hg) is 200.59 grams per mole.
What is the mass of mercury Hg?
The atomic mass of mercury (Hg) is approximately 200.59 grams per mole.
What mass of Hg will occupy a volume of 50.0 mL?
The density of mercury (Hg) is 13.6 g/mL. Therefore, the mass of Hg that will occupy a volume of 50.0 mL can be calculated using the formula: mass = volume x density. Substituting the values, we get mass = 50.0 mL x 13.6 g/mL = 680 grams.
How many atoms are in 11.5 g Hg?
To find the number of atoms in 11.5 g of mercury (Hg), first determine the number of moles using its molar mass, which is approximately 200.59 g/mol. Divide the mass by the molar mass: ( 11.5 , \text{g} \div 200.59 , \text{g/mol} \approx 0.0573 , \text{mol} ). Then, multiply the number of moles by Avogadro's number ( (6.022 \times 10^{23} , \text{atoms/mol}) ): ( 0.0573 , \text{mol} \times 6.022 \times 10^{23} \approx 3.45 \times 10^{22} ) atoms. Thus, there are approximately ( 3.45 \times 10^{22} ) atoms in 11.5 g of Hg.
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.
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
What is the atomic mass of hg?
The atomic mass of mercury (Hg) is 200.59 grams per mole.
What is the mass of mercury Hg?
The atomic mass of mercury (Hg) is approximately 200.59 grams per mole.
What does Hg stand for in chemistry?
Hg stands for mercury metal..only liquid state meta
What is the symbol and the number of mercury?
We use Hg as the symbol. Atomic number of Hg is 80.
If 60.2 grams of Hg combines completely with 24.0 grams of Br to form a compound what is the percent composition of Hg in the compound?
To find the percent composition of mercury (Hg) in the compound, you first calculate the molar mass of each element. Then, find the molar mass of the compound by adding the molar masses of Hg and Br. Divide the molar mass of Hg by the molar mass of the compound and multiply by 100 to get the percentage. In this case, the percent composition of Hg in the compound is approximately 71%.
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 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 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 mass of Hg will occupy a volume of 50.0 mL?
The density of mercury (Hg) is 13.6 g/mL. Therefore, the mass of Hg that will occupy a volume of 50.0 mL can be calculated using the formula: mass = volume x density. Substituting the values, we get mass = 50.0 mL x 13.6 g/mL = 680 grams.
What is the oxidation number of mercury 1?
+1 for Hg in the Hg22+ ion
