Question

How many molecules are present in 1gram of hydrogen gas?​

Answer 1

Answer:

the molecular mass of Hydrogen is 1gram/mole, there is 1 mole of hydrogen in 1 gram of hydrogen atoms. For every mole, there are 6.02*10^23 atoms so in 1 gram of hydrogen there are 6.02*10^23 hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000

Answer 2

Answer:

So in 1 g of hydrogen it is 26. 02×1023molecules=3.
