How many grams of magnesium metal will react completely with 5.2 liters of 4.0 m hcl?

mg (s) + 2 hcl (aq) --> mgcl2 (aq) + h2 (g)

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots
