How many molecules are in 54.0 grams of CO2?

Chemistry
1 answer:
mote1985 [20]2 years ago
6 0

Answer:

7.38654 in 54 grams

Explanation:

To get moles, you divide grams of a substance by molecular weight. The molecular weight of CO2 is 44 g/mol. 54g divided by 44/mol  is 1.227moles.

You then need to multiply moles by Avogadro’s constant (6.022x10^23). That gives you 7.38654x10^23 molecules in 54 grams of CO2.

What is the relationship between the density and position of each Earth layer?
vredina [299]

Answer:

The atmosphere and Earth's interior are layered by density. Gravity pulls more strongly on denser materials so denser materials are at the center of things. Earth's core, at its center, is denser than its crust. The lowest layer of the atmosphere is denser than the upper layer.
