Answer 1

Explanation:

plz like this Answer

Gram molecular mass of CO2 = 12 + (16 Χ 2). = 12 + 32. = 44 g. Mass of 1 mole (6.023 X 10 23 molecules) of CO2 is about 44g.

Answer 2

1 mole of a substance is equal to its molecular mass expressed in terms of grams.

Gram molecular mass of CO2 = 12 + (16 Χ 2)

= 12 + 32

= 44 g

Mass of 1 mole (6.023 X 1023 molecules) of CO2 is about 44g.
