A. An 18-mg strip of magnesium metal reacts in 5.0 mL of 3.0 M HCl over a given time period. Evaluate the ratio molHCl/molMg for the reaction. b. What are the correct labelings of the axes for the data plot?

A. We know that

No of mol of Mg is mass/ molarmass

So

= 18/24 = 0.75 milimol

no of mol of HCl is mass/molar mass

So

= 5 x 3 = 15 milimol

ratio = mol HCl / mol Mg = 15/0.75 = 20

B.

X axes will be in seconds

Y axe will be in millimol
