14. what is the mass of 1 mole of strontium atoms? 0.05 g 87.62 g 6.02 x 10^23 g 1.76 x 20^34 g clear all

Answer:

B. 87.62 g

Explanation:

Step1: Recall molar - mass concept

The molar mass of an element (in g/mol) is numerically equal to its atomic mass (in amu).

Step2: Find strontium's atomic mass

Strontium (Sr) has an atomic mass of approximately 87.62 amu.

Step3: Determine mass of 1 - mole

The mass of 1 mole of any substance is equal to its molar mass. So, the mass of 1 mole of strontium atoms is 87.62 g.
