What is the mass in amu of 16 mercury atoms?
What is the mass in amu of 16 mercury atoms?
Atomic mass of Mercury is 200.59 u.
How many atomic masses does mercury have?
80Mercury / Atomic number
How many grams are there in mercury?
One milliliter of mercury converted to gram equals to 13.53 g.
How do you calculate atomic mass in grams?
It is determined by taking the atomic weight for an element on the periodic table and expressing it in grams. So, for example, sodium (Na) has an atomic weight of 22.99 u, so it has a gram atomic mass of 22.99 grams. So one mole of sodium atoms has a mass of 22.99 g.
What is the mass of 1 atom of mercury?

Is atomic mass and mass number same?
Key Takeaways: Atomic Mass Versus Mass Number The mass number is the sum of the number of protons and neutrons in an atom. It is a whole number. The atomic mass is the average number of protons and neutrons for all natural isotopes of an element. It is a decimal number.
How much does a gram of mercury weigh?
One gram of mercury converted to pound equals to 0.0022 lb. How many pounds of mercury are in 1 gram? The answer is: The change of 1 g ( gram ) unit of a mercury amount equals = to 0.0022 lb ( pound ) as the equivalent measure for the same mercury type.
What is 1g atomic mass?
The gram atomic mass of an element can be defined as the mass of one mole of atoms of a particular element. It is numerically equivalent to the value of the element’s atomic mass unit but has its unit in grams. For example, the mass of one atom of carbon is 12υ or twelve atomic mass units.
How many atomic mass are in a gram?
Since a carbon atom weighs 12 AMU, one AMU is equivalent to 1.66 x 10-24 grams. Conversely, one gram is equivalent to 6.022 x 1023 AMU, which is Avogadro’s number.

How do you convert from moles to grams?
You have three steps to convert mole values to grams.
- Calculate how many moles are mentioned in the question.
- Find the molar mass of the substance.
- Multiply both the values.
What is the difference between atomic mass and gram atomic mass?
Atomic mass units (amu) are units that are used to measure the mass of individual atoms or molecules. Grams (g) are units that are used to measure very large numbers of atoms or molecules. So, in order to compare these two units you have to be prepared to use very small numbers.
What is the mass of one atom?
The mass of a single carbon atom is 1.994 x 10-23 g. The mass of a single atom is an extremely small number! This is why chemists use Avogadro’s number. It makes working with atoms easier because we work with moles rather than individual atoms.
What is 1 gm atom?
Hint: One gram atom means the mass of one mole of an element equal in grams to the atomic weight. One gram atom of oxygen is defined as the atoms present in one gram of oxygen atom.
What is the atomic weight of Hg?
200.59 uMercury / Atomic mass
What is the mass of 1 mole of mercury?
200.59 g
a) The atomic weight of mercury is 200.59, and so 1 mol Hg weighs 200.59 g.
What does mercury element weigh?
The element shares group IIB of the periodic table with zinc and cadmium. The atomic number of mercury is 80; its atomic weight is 200.59.
How do you find the atomic mass in grams?
It’s easy to find the mass of a single atom using Avogadro’s number. Simply divide the relative atomic mass of the element by Avogadro’s number to get the answer in grams.
What are 5 common uses of mercury?
Mercury is used in thermometers and traditional blood pressure monitors.
What does the atomic mass tell us?
The atomic mass of an element (the average of its isotopes) tells me what weight I need in a mole, useful to make it react chemically with other compounds or elements. The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. It is traditionally represented by the symbol Z.
What is atomic mass and how is it determined?
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
How to calculate atomic mass?
number of protons = atomic number
