Question

Which weighs more, 0.50 mole oxygen atoms or 4 mole of hydrogen atoms?

Answer 1

Answer:

0.5 moles of oxygen weighs more than that of the 4 moles of hydrogen.

Explanation:

Atomic mas of oxygen = 16.0 g/mol

mass of 0.50 moles of oxygen atom =

$0.5 mol\times 16.0 g/mol= 8.0 g$

Atomic mas of hydrogen = 1.0 g/mol

Mass of 4 moles of hydrogen atom =

$4 mol\times 1.0 g/mol= 4.0 g$

0.5 moles of oxygen weighs more than that of the 4 moles of hydrogen.

Answer 2

0.50 moles of oxygen weighs more as compare to the 4 moles of hydrogen atoms.

How we calculate weight?

We calculate the weighs by using below formula:

n = W/M, where

n = no. of moles

W = weight to find ?

M = molar or atomic mass

Weight of oxygen atoms is calculate as follow:

W = 0.50mole (given) × 15.99g/mole = 7.9 grams

Weight of hydrogen atoms is calculate as follow:

W = 4mole (given) × 1g/mole = 4 grams

Hence, weight of oxygen atoms is more as compare to hydrogen atoms.
