Answer

Explanation:

Step1: Recall uranium's atomic mass

The atomic mass of uranium (U) is approximately 238 u. One - mole of an element has a mass in grams equal to its atomic mass. So one mole of uranium is 238 grams.

Step2: Recall the concept for mole - mass relationship

The mass of one mole of an element is given by its atomic mass (expressed in grams). Molar parity is not the correct term for this relationship.

Step3: Recall carbon's atomic mass

The atomic mass of carbon (C) is approximately 12.01 u. So one mole of carbon weighs 12.01 grams.

Answer:

  1. B. 238
  2. A. atomic mass
  3. B. 12.01
