What else can I help you with?
What does an element's molar mass tell you about the element?
An element's molar mass represents the mass of one mole of that element in grams. It tells you the average atomic mass of the element, which is the sum of the protons and neutrons in the nucleus of its atoms. Molar mass helps in determining the amount of substance in moles when given the mass of the sample.
Which element has with mass number 27?
The element with mass number 27 is cobalt, which has 27 as its atomic mass.
What element has a mass number of 197?
Hafnium is the element that has a mass number of 179. Its color is silver, its structure is hexagonal, while the number of neutrons is 106.
What element has a relative atomic mass of 15.5?
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
What is the element that has a mass of 55 and contains 30 neutrons in its atoms?
The element with a mass of 55 and 30 neutrons in its atoms is zinc (Zn). This can be determined by subtracting the number of neutrons from the atomic mass of the element.
What is the atomic mass of ziconium?
Zirconium is a metal element. Atomic mass of it is 91.
What is the atomic mass of Zerconium?
Zerconium is a metal element. Atomic mass of it is 91.
231PA91 has how many neutrons?
The element proactinium-231 has 140 neutrons (element number 91, 91 protons).
What determines an element's mass?
the mass of protons + the mass of neutrons = mass of the element
What element has the symbol Pa?
Protactinium
If element X has 91 protons how many electrons does it have?
If element X has 91 protons, it is element Protactinium (Pa) on the periodic table. In a neutral atom, the number of electrons equals the number of protons, so element X would also have 91 electrons.
What do you call the mass of an element?
The mass of an element is known as it's ATOMIC Mass.
What is the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
The molar mass of an element is equal to?
The element's average atomic mass.
How to find the mass of an element in a chemical compound?
To find the mass of an element in a chemical compound, you can use the atomic mass of the element from the periodic table and the number of atoms of that element in the compound. Multiply the atomic mass by the number of atoms, and you will get the mass of that element in the compound.
How many protons are in element 91?
91. Atomic number is equal to the number of protons.
What element has a mass number of 85?
Rubidium is a metal element. Mass number of it is 85.
