what is the molar mass of iodine? remember to round to the hundredths place from the periodic table. 126.90 g/mol 253.80 g/mol 53.00 g/mol 114.80 g/mol

Answer

Explanation:

Step1: Identify iodine in periodic table

Iodine (I) has an atomic mass of 126.90447 from the periodic - table. When rounded to the hundredths place, it is 126.90. But iodine in its elemental form is $I_2$.

Step2: Calculate molar mass of $I_2$

The molar mass of $I_2$ is $2\times126.90\ g/mol = 253.80\ g/mol$.

Answer:

B. 253.80 g/mol
