Question

how do i find the mass of 0.5 moles of nitrogen gas

Answer 1

★ Ello ★



mole = mass of substance / molecular mass


0.5 = mass of N2 gas / 2 × 14



{ mass of one molecule of N2 gas is 28 }


so,


mass of 0.5 mole of nitrogen is =>

0.5 × 28

=> 14


therefore ,

your answer is


★ 14 g ★



hope it helps you dear !!



$thanks$

Answer 2

HEYA Frnd. ......... ☺

We know that;

Mass of N2 gas (M) = 2 × 14
=> 28 g

Given moles (n) = 0.5

==================


n = m/M

n = No. Of Moles

M = Molar mass

m = given mass ( asked in the question to be found)

===================

=> 0.5 = m / 28

=> m = 0.5 × 28

m => $\boxed { m = 14 g}$--.....☆⭐ANS⭐☆

HOPE IT WILL HELP YOU. . . ☺
