3 0

Answer:

The mass in grams is 487.5 for methanol.

Explanation:

We must calcuate the grams of a compound through the molar mass of it.

Molar mass of methanol: 32.04 g/mol

We know that 1 mol has NA molecules and they weigh 32.04 g so, this is the rule of three we must make:

6.02x10²³ molecules _____ 32.04 g

9.16x10²⁴ molecules _____ (9.16x10²⁴ . 32.04) / 6.02x10²³  = 487.5 g
