Question

a single chlorine atom weighs 35.45 g. periodic table of elements chemical group block trends pub chem true false

Explanation:

Step1: Recall the concept of atomic mass unit

The atomic mass of an element is given in atomic mass units (amu). The molar mass of chlorine is approximately \(35.45\space g/mol\).

Step2: Understand the difference between molar mass and mass of a single atom

Molar mass is the mass of \(1\space mol\) of a substance. \(1\space mol\) of any substance contains \(6.022\times 10^{23}\) atoms (Avogadro's number). So, the mass of a single chlorine atom is \(\frac{35.45\space g/mol}{6.022\times 10^{23}\space atoms/mol}\approx5.89\times 10^{-23}\space g/atom\)

Answer:

false
