Answer:
3.17mol
Explanation:
moles of Na = m/M ; Where M - molar mass of Na which is 23
moles of Na = 73/23 =3.17mol
but from the eqn n(Na) : n(NaOH) = 2:2 = 1:1
: . moles of NaOH is also 3.17mol
1.
n = m/2.016 g/mol = V/22.4 l
V = 22.4 l
Hence,
m = 2.016 g ≈ 2.02 g
B.) 2.02 g
2.
Balancing the equation, we get,
Mg + 2HCl → MgCl2 + H2
PV = nRT
V = nRT/P
V = 1.5 mol × 8.314 atm/(mol.K) × 298 K/(0.96 atm)
V = 3871.206
V ≈ 38.2 l
Because you need to know what you are looking for before actually trying something so you can prevent any accidents by doing stuff at random
