How many grams of co2 are used when 6.5 g of o2 are produced

Answer : The mass of used are 8.8 grams.

Solution : Given,

Mass of = 6.5 g

Molar mass of = 32 g/mole

Molar mass of = 44 g

First we have to calculate the moles of .

Now we have to calculate the moles of

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 1 mole of produced from 1 mole of

So, 0.20 mole of produced from 0.20 mole of

Now we have to calculate the mass of

Therefore, the mass of used are 8.8 grams.

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.

explanation:

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
