Asample of glucose, ceh120e, contains 1.03 x 1025 atoms of carbon. how many atoms of hydrogen does it contain?

2.06 × 10^25

The formula for glucose is C6H12O6.

One molecule of glucose contains 6 C atoms and 12 H atoms, so the ratio is 12 H atoms/6 C atoms.

No. of H atoms = 1.03 × 10^25 atoms C × (12 atoms H/6 atoms C)

= 2.06 × 10^25 atoms H.

neutrons are in the middle of the atom and the electrons, which are much smaller.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
