The atomic mass of an atom of carbon is 12 amu, and the atomic mass of an atom of oxygen is 16 amu. to produce co2, 16 g of oxygen combine with 12 g of carbon. to produce co2, 32 g of oxygen combine with 12 g of carbon. the ratio of the mass of oxygen in co2 to the mass of oxygen in co is a 8: 3. b 1: 1. c 2: 1. d 1: 2.

Answer : The correct option is, (C) 2 : 1

Explanation : Given,

Atomic mass of carbon = 12 amu

Atomic mass of oxygen = 16 amu

To produce , 16 g of oxygen combine with 12 g of carbon. That means,

Mass of oxygen in CO = 16 g

Mass of carbon in CO = 12 g

To produce , 32 g of oxygen combine with 12 g of carbon. That means,

Mass of oxygen in = 32 g

Mass of carbon in = 12 g

Now we have to determine the ratio of the mass of oxygen in to the mass of oxygen in .

Therefore, the ratio of the mass of oxygen in to the mass of oxygen in is, 2 : 1

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

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
