Question

answer with calculation​

Answer 1

Answer:

6.023*10^24 molecules(10 moles)of NH3is the heaviest.

Explanation:

Weight of 10 moles of H2 is 10*2=20 gm

Weight of 22.4L(1 mole) of CH4 is 1*16=16 gm

Weight of 6.023*10^24 molecules(10 moles)of NH3 is 10*17=170 gm

Weight of 14 gm(0.5 moles) of N2 is 0.5*28=14

Hope this helps you..

Answer 2

Answer: OPTION(3) 6.023×10²⁴ MOLECULES OF NH₃.

Explanation:

THE BASIC EQUATION TO KNOW IS

NUMBER OF MOLES=WEIGHT/GRAM MOLECULAR WEIGHT=VOLUME AT STP/22.4L=NUMBER OF MOLECULES/AVAGADRO NUMBER.

SO FOR

1)WEIGHT=10×2=20grams

2)BY USING ABOVE EQUATION NUMBER OF MOLES=1

   SO WEIGHT=16grams.

3)BY USING ABOVE EQUATION NUMBER OF MOLES=10

   SO WEIGHT=170grams.

4) 14grams.

SO HEAVIEST IS 6.023×10²⁴ MOLECULES OF NH₃.

HOPE IT HELPS YOU....................
