Question

What is the mass of aluminum metal that reacts to give 1.5 g of hydrogen gas? 2 Al(s)+6 HCl(aq)2 AICI3(aq) + 3 H2(g)

science chemistry

Answer 1

Answer #1

2Al (s) + 6 HCl (aq) ----------> 2 AlCl3 (aq) + 3 H2 (g)

53.963 g 6.00 g

?? 1.5 g

mass of Al metal = 1.5 x 53.963 / 6

= 13.5 g

mass of Aluminium metal = 13.5 g
