0.46 moles (230/100 x 2)
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.
Starting with the formula: 2HNO3 --> H2O + NO2 If you have 0.4 moles of nitric acid (HNO3), you will get half the number of moles of NO2. So, you will have 0.2 moles of nitric acid.
12 moles Li
20 moles of NaOH needed to neutralize 20 moles of nitric acid
Not normally. Hydrochloric acid will dissolve carbonates, so marble (calcium carbonate) would be dissolved but many rocks are impervious to acids.

All of the moles of pure acid will have dissolved in the flask.

moles = weight (in g) / molecular weight = 5 / 90 = 0.056 moles
In the acid-base reaction where sodium hydroxide and sulfuric acid react, the formula is: H2SO4 + 2NaOH --> Na2SO4 + 2H2O. The coefficients shown are necessary to uphold the law of conservation of mass. So, if you have 17 moles of sulfuric acid, you will need twice as many moles of sodium hydroxide, so the answer is 34 moles NaOH.
Sulfuric acid is not obtained from water.
The answer is 699 moles perchloric acid.
Starting with the formula: 2HNO3 --> H2O + NO2 If you have 0.4 moles of nitric acid (HNO3), you will end up with half the moles of nitrogen dioxide (NO2)...so you will have 0.2 moles.
The answer is 15 moles.
