When creating mixture the amount of hydrogen gas is directly related to the concentration of the acid mixture, the higher the concentration level The more hydrogen gas would be produced.
John Dalton used experiments and scientific tools to study matter
1. 92 g
2. 5.4 g
3. 0.217 moles
<h3>Further explanation </h3>
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
1. the mass of 4 moles of Na(MW= 23 g/mol)
2. the mass of 0.3 moles of water(MW=18 g/mol)
3. the number of moles found in 10g of ethanol C2H5OH(MW=46 g/mol) :
You can just google a picture of the periodic table!
Some examples are hydrogen, helium, sodium, titanium, carbon, potassium, nitrogen, neon, lithium, calcium, fluorine, oxygen, boron, etc.
