Answer:
VH2SO4 = 145.3 mL
Explanation:
Mw BaO2 = 169.33 g/mol
⇒ mol BaO2 = 53.5g * ( mol BaO2 / 169.33 g BaO2) = 0.545 mol BaO2
⇒according to the reaction:
mol BaO2 = mol H2SO4 = 0.545 mol
⇒ V H2SO4 = 0.545 mol H2SO4 * ( L H2SO4 / 3.75 mol H2SO4 )
⇒V H2SO4 = 0.1453 L (145.3 mL)
You want to convert Euros / kg to Dollars / pound
So you'll have to multiply the price (Euros / kg) by the exchange rate (Dollars / Euro) to get a number that has units of Dollars / kg.
Euros Dollars Dollars
------- x --------- = --------
kg Euro kg
Then you have to multiply the number of kg in a pound (which has units of kg / pound) to get a number in units of Dollars / pound. This number is 2.2.
Dollars kg Dollars
-------- x -------- = --------
kg pound pound
So the answer would be 1.75 * 1.36 / 2.2 = 1.08 dollars / pound.
