about 6 gram per mole
about 6.02 x 10^23 (602,200,000,000,000,000,000,000) grams per mole

Explanation:

Step1: Analyze the periodic table info

The atomic weight of hydrogen (from the table) is ~1.008 (or 1.0079), which is its molar mass (grams per mole).

Step2: Evaluate options

• "about 1 gram per mole" matches the molar mass of H (≈1 g/mol).
• "about 6 gram per mole" is incorrect (not H's mass).
• The last option is Avogadro’s number (molecules in a mole), not molar mass.

Answer:

A. about 1 gram per mole (assuming the first option is labeled A, as per typical multiple - choice formatting with the first option being "about 1 gram per mole")
