Answer:
The density is
Explanation:
From the question we are told that
the lattice constant is 
The density of Copper (
) is mathematically represented as

Where Z is the number of units in a unit cell and for BCC crystals Z =2
M is the molar mass of copper which same for Copper with a value of

is the Avogadro's constant with a value of 
Substituting values

The answer is dissolved in water, because in chemistry, (aq) is shorthand for aqueous solution.
Answer:
A) 122 atm
Explanation:
PV = nRT
Solve for P --> P = nRT/V
n = 10.0 mol + 5.0 mol = 15.0 mol
R = 0.08206 L atm / mol K
T = 25 + 273 = 298 K
V = 3.0
P = (15.0)(0.08206)(298) / (3.0) = 122 atm
