It is the darmstadtium element that has the electron configuration above and the atomic number of 110
A is the answer im pretty sure
Isotopes are the atoms of the same element with same atomic number but different mass number isotopes of same element have same chemical properties due to same number of electrons atomic number of an atom is the number of electrons protons in it and mass number is the sum of protons
Answer:
9.15 × 10²³ molecules of N₂O present.
Explanation:
Given data:
number of moles = 1.52 mol
molar mass of N₂O = 44.013 g/mol
number of molecules = ?
Solution:
First of all we will calculate the mass of 1.52 mol.
mass = number of moles × molar mass
mass = 1.52 × 44.013 g/mol
mass = 66.9 g
Now we will find the number of molecules by using Avogadro number,
The number 6.022×10∧23 is called Avogadro number and it is the number of atoms or molecule in one gram atom of an element or one gram molecule of a compound.
44.013 g of N₂O = one mole of N₂O= 6.02 × 10²³ molecules
For 66.9 g:
66.9 g/ 44.013 g × 6.02 × 10²³ molecules
9.15 × 10²³ molecules of N₂O present
