Answer 2

please mark me brainliest

one mole of Zn reacts with 2 Moles of HCl,

So, 4.25 moles of Zn will react with 4.25 x 2 = 8.5 moles of HCl is required to completely react with 4.25 moles of Zn

So, the mass of one HCl molecule 1 + 35.5 = 36.5

Mass of 8.5 moles of HCl = 8.5 x 36.5 = 310.25 g of HCl is required
