Answer:
24 atoms of H or 1.4 x 10²⁵ hydrogen atoms
Explanation:
simple method
1 H₂O has atoms of hydrogen and 1 atom of oxygen
while 12H₂O will have 24 atoms of hydrogen and 12 atom of oxygen
by Avagadros number
molar mass of water H₂0=18.01528 g/mol
1 mole of H₂0 have 2 moles of Hydrogen
one mole of water= 6.02⋅10²³water molecules =1.2 x 10²⁴hydrogen atoms
12 mole of H₂O = 1.2 x 10²⁴ x 12= 1.4 x 10²⁵ hydrogen atoms
<u />
1.4 x 10²⁵ hydrogen atoms in 12 moles of H₂O

When temperatures rise, the body reacts by increasing blood flow to the skin's surface, taking the heat from within the body to the surface. This means sweat. ... If, as in the UK, our skin temperature is warmer than the external temperature we are also able to lose heat to the environment, termed 'dry heat loss'.
Weathered debris is a result of FROST WEDGING.
Frost wedging refers to the process by which water freeze and thaw continuously over a period of time. Rocks usually contain crevices which are filled with water. Due to the extreme temperature changes during the night and day and during the course of season changes, the water in the crevices freeze and thaw continuously leading to the cracking of the rocks as a result of the expansion and contraction of the rocks.<span />
