1000dm = 0.1 km
The picture below is proof that it is correct.
Aluminum reacts with hydrochloric acid to produce aluminum chloride and hydrogen gas. 2 al(s) + 6 hcl(aq) → 2 alcl3(aq) + 3 h2(g) what mass of h2(g) is produced from the reaction of 1.35 g al(s) with excess hydrochloric acid?
Answer:
1000cm³=1litre
1.5x10^6cm^3=1.5x10^6cm^3/1000litre=1.5×1000000/1000=1.5×1000=1500litres.
