2HCl+Na2SO4--->2NaCl+H2O, If you start with 20 grams of hydrochloric acid, how many grams of sulfuric acid will be produced? Round to the nearest tenth. Don't forget the units
You have a really odd equation for your reaction.
It should be 2HCl+Na2SO4--->2NaCl+H2SO4
To determine the grams of sulfuric acid produced in the given chemical reaction, we need to start by finding the number of moles of hydrochloric acid (HCl) and use the mole ratio to convert it to moles of sulfuric acid (H2SO4). Finally, we can convert moles to grams using the molar mass of sulfuric acid.
1. Find the number of moles of HCl:
To do this, we need to know the molar mass of hydrochloric acid (HCl).
The molar mass of HCl is 1.007 grams/mol for hydrogen (H) + 35.453 grams/mol for chlorine (Cl). Thus, the molar mass of HCl is 36.460 grams/mol.
Given that we have 20 grams of HCl, we can calculate the number of moles:
Number of moles = mass of substance / molar mass
Number of moles of HCl = 20 grams / 36.460 grams/mol
2. Use the mole ratio:
According to the balanced chemical equation, the mole ratio between HCl and H2SO4 is 2:1. This means that for every 2 moles of HCl, we will produce 1 mole of H2SO4.
So, we will multiply the number of moles of HCl by the mole ratio (1/2) to find the moles of H2SO4.
Moles of H2SO4 = Number of moles of HCl * (1/2)
3. Convert moles to grams of H2SO4:
To do this, we need to know the molar mass of sulfuric acid (H2SO4).
The molar mass of H2SO4 is 1.007 grams/mol for each hydrogen (H), 32.060 grams/mol for sulfur (S), and 15.999 grams/mol for each oxygen (O). Thus, the molar mass of H2SO4 is 98.090 grams/mol.
Finally, we can calculate the grams of H2SO4:
Grams of H2SO4 = Moles of H2SO4 * Molar mass of H2SO4
Please note that the molar mass values used in this explanation are approximate and rounded to the nearest thousandth.
Using this information, you can now calculate the grams of sulfuric acid produced in the given chemical reaction.
