Answer:
Because some of the symbols are from Latin
They are:
Mercury - Hg - Hydrargyrum
Potassium - K - Kalium
Silver - Ag - Argentum
Gold - Au - Aurum
Sodium - Na - Natrium
Tin - Sn - Stannum
Iron - Fe - Ferrum
Lead - Pb - Plumbum
Copper - Cu - Cuprum
Antimony - Sb - Stibium
Tungsten - W - Wolfram
Assuming that the gas is ideal, we can use the ideal gas equation PV=nRT to calculate for the number of moles. Then, multiply the molar mass of the gas to obtain the mass. We do as follows:
PV = nRT
n = PV / RT
n = 1.1 atm (3.7x10^9 L) / 0.08205 L-atm/mol-K (280.15) = 177061931.3 mol H2
Mass = (177061931.3 mol H2) 18.02 g/mol ( 1 kg / 1000g) ( 2.2 lb / 1 kg ) = 7019443.21 lb H2
1) first, write the balanced equation:
2KOH + H₂SO₄ ---> 2H₂O + K₂SO₄
2) convert grams of sulfuric acid to mole using it's molar mass.
molar mass H₂SO₄= (2 x 1.01) + 32.0 + (4 x 16.0)= 98.0 g/mol
2.70 grams (1 mol/ 98.0 grams)= 0.0276 moles
3) use the mole to mole ratio from the balanced equation to change the moles of sulfuric acid to moles of potassium, hydroxide (KOH).
ration--->2 mol KOH = 1 mol H₂SO₄
0.0276 mol H₂SO4 (2 mol KOH/ 1 mol H₂SO₄)= 0.0551 mol KOH
4) convert moles to grams using the molar mass of KOH
molar mass of KOH= 39.1 + 16.0 + 1.01= 56.1 g/mol
0.0551 mol (56.1 grams/ 1 mol)= 3.09 grams
