    The mass percent of gold in the rock is 2.500 %

    Explanation:

    Step 1: Data given

    Mass of the rock = 12000 grams

    Mass of gold = 300.0 grams

    Step 2: Calculate mass %

    Mass % = mass of gold / mass of gold

    Mass % = (300.0 grams / 12000 grams) * 100 %

    Mass % = 2.500 %

    The mass percent of gold in the rock is 2.500 %
