Question

Calculate and compare the masses of 0.5 mole of CO and 0.5 mole of nitrogen.​

Answer 1

Answer:

please thanks for the answer

please mark as brainliest answer

Explanation:

so mass = no of moles * molecular mass i. e for co 0.5*14=7 for n2 0.5* 14 = 7 hence they have same masses.

Answer 2

molecular mass of CO is 28 .

1 mole of CO2 = 28 gm molecular weight

so , 0.5 mole = 14 gm

now ,

molecular mass of N is 28

1 mole of N2 = 28 gm

so , 0.5 mole = 14 gm

compare = same mass at 0.5 mole !!
