Basically, carbon (C2) burns in the presence of adequate Oxygen (O2) to form carbon dioxide. Carbon is Quadro valent and is able to accept four more electrons. Oxygen has two electrons and hence, readily reacts with carbon to help break and make bonds. The chemical equation of carbon dioxide (CO2) is

carbon + oxygen → carbon dioxide or C2 + O2 = CO2

Aluminum has a density of 2.70 g/mL. Calculate the mass (in grams) of a piece of aluminum having a volume of 264 mL .
gavmur [86]
The formula for density is:

D = m/v

We can use the formula to figure out the mass because we already know two of the three values (we are given the density and volume), so we only have to solve for <em>m. </em>If we plug our given values into the formula, we get:

2.70 = m / 264

Now, all we need to do is solve for <em>m</em>. The goal is to get <em>m</em> on one side of the equation, and all we have to do is multiply each side of the equation by 264:

264 × 2.70 = (m÷264) × 264

264 × 2.70 = m

m = 712.8

The mass of the piece of aluminum is 712.8 grams.
