Answer is: 88,9 g of AlCl₃.
N(AlCl₃) = 4,00 · 10²³.
n(AlCl₃) = N(AlCl₃) ÷ Na.
n(AlCl₃) = 4 · 10²³ ÷ 6·10²³ 1/mol
n(AlCl₃) = 0,66 mol.
m(AlCl₃) = n(AlCl₃) · M(AlCl₃)
m(AlCl₃) = 0,66 mol · 133,35 g/mol = 88,9 g.
Na - Avogadro number.
M - molar mass.
n - amount of substance

Answer:
The time you will get to Atlantic City is 3 pm
Explanation:
Given;
speed limit, v = 50 km/h
distance to be traveled, d = 150km
The time of the motion is given as;
time = distance / speed
t = (150 km) / (50 km/h)
t = 3 hours
Thus, if you leave your home at noon, the time you will get to Atlantic City is given as;
time to get home = 12 pm + 3hours = 3 pm
Therefore, the time you will get to Atlantic City is 3 pm
