The drain cleaner, Drainex contains small bits of aluminium which react with caustic soda to produce dihydrogen. What volume of dihydrogen at 20∘C and one bar will be released when 0.15 g of aluminium reacts?
At STP | Given conditions |
P1=1 atm | P2=1 bar=0.987 atm |
V1=0.186 L | V2=? |
T1=273 K | T2=273+20=293 K |
