Calculate the percent by mass of carbon in co2 (carbon dioxide).

The answer to your question is 27.3 %

Explanation:

Percent by mass = ?

Process

1.- Calculate the atomic mass of carbon using the periodic table

Atomic mass = 12g

2.- Calculate the molecular mass of CO₂.

Carbon = 12

Oxygen = 16 x 2 = 32

Total = 12 + 32 = 44g

3.- Calculate the percent by mass of carbon using proportions

                          44g 100%

                           12 g  x

                            x = (12 x 100) / 44

                            x = 1200 / 44

                            x = 27.3 %

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

your answer would be “dry”
