Answer 2

Answer:

D. 180.1 g/mol

Explanation:

Add up each of the masses of the elements in glucose and multiply them by the subscript number.

Carbon: 12.01 * 6 = 72.06

Hydrogen: 1.008 * 12 = 12.096

Oxygen: 16.00 * 6 = 96

72.06 + 12.096 + 96 = 180.156 g/mol ≈ 180.1 g/mol

*Molecular masses vary depending on which measurement / periodic table you use, so expect to be within a range, not exactly the same. My answer was closer to 180.2 g/mol, but it's still acceptable.
