What is the mass, in grams, of 9.16×10^24 molecules of methanol (ch3oh)?

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

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
