Delvig [45]

Answer:

The unit cell edge lenght in pm is equal to 361 pm

Explanation:

Data provided:

ρ=Copper density=8.96 g/cm3

Atomic mass of copper=63.54 g/mol

Atoms/cell=4 atoms (in theory)

Avogadro's number=6.02x10^{23} atoms/mol

Since copper has a cubic structure, its cell volume is equal to a^{3}, which can be obtained through the relationship:

cell volume=\frac{(atoms/cell)(atomic mass)}{(density)(Avogadros number)}

Substituting the values:

cell volume=\frac{(4 atoms)(63.54 g/mol)}{(8.96 g/cm3)(6.02x10^{23}) }=4.71x10^{-23}cm^{3}

clearing, we have:

a=\sqrt[3]{4.71x10^{-23}cm^{3}  }=3.61x10^{-8}cm

We convert from centimeter to picometer, 1cm=1x10^{10}pm

a=3.61x10^{-8}cmx\frac{1x10^{10}pm }{1cm} =361 pm

What occurs along a convergent plate boundary
HACTEHA [7]
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

Which statement accurately describes the origin and expansion of the universe? As the universe continues to expand, it gradually
dimulka [17.4K]

The answer is; Cosmic background radiation is leftover thermal energy from the big bang.

Called the coming microwave background the  weak radiation fills the universe more or less uniformly. This radiation is the fossil remnants of the postulated big band at the beginning of the universe. The photos produced at the time continue to travel through the universe growing fainter over time and have fallen in the microwave range of the electromagnetic spectrum now.

What is the molarity of a solution in which 0.321 g of calcium chloride is dissolved in 1.45 L water?
lana66690 [7]

Answer:

Molarity = 0.002 M

Explanation:

Given data:

Mass of calcium chloride = 0.321 g

Volume of water = 1.45 L

Molarity of solution = ?

Solution:

Molarity = number of moles / volume in litter.

We will calculate the number of moles of calcium chloride first.

Number of moles = mass/molar mass

Number of moles = 0.321 g/ 110.98 g/mol

Number of moles = 0.003 mol

Molarity:

Molarity = 0.003 mol / 1.45 L

Molarity = 0.002 M
