How many grams of oxygen does it take to produce 9.60 moles of carbon dioxide?

307.2grams of oxygen does it take to produce 9.60 moles of carbon dioxide.

Solution given:

1 mole of Oxygen=16g

Explanation:

C +O2=CO2

1 mole+ 1 mole =1 mole

12g. + 32g = 44g

we have

1 mole of carbon dioxide=12g of C and 32 g of O2

9.6 mole of carbon dioxide=12*9.6g of C and 32 *9.6g of O2

grams of oxygen needed is 32*9.6=307.2g

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
