Question

how many grams does an atom of Hydrogen weigh​

Answer 1

Answer:

A gram molecule is the number of molecules present in one mole of that substance instead of the atoms.

For example, in CaCO3, one mole contains five gram atoms (one of Ca, one of C and three of O); one gram molecule and two gram ions (one of Ca2+ and one of CO32-)

Let the weight of one atom of hydrogen be X

Weight of one mole of hydrogen = 1.008g

Weight of 6.022 × 1023 atoms of hydrogen = 1.008 g

As 6.022 × 1023 atoms of hydrogen weighs 1.008g,

∴ 1 atom of hydrogen weighs

X = 1/ 6.022 × 1023

X = 1.66058 × 10-24

The weight of 1 atom of hydrogen is calculated as 1.66058 × 10-24 grams.
