Answer:
5.96 g/cm^3
Explanation:
Corner atom = 1/8
Atoms in center = 1
Atoms in face of the cube= 1/2
Molar mass of V = 50.94 g/mol <em>(from period table)</em>
1 mole = 6.02x10^23
<em>In BCC unit cell:</em>
(8 x 1/8)+ 1=2 per 1 unit cell
<em>Mass: </em>2(50.94g)/6.02x10^23 = 1.69x10^-22 g/unit cell
305pm=(305x10^-12m÷10^-2m) x (1mL÷1cm^3)
= 2.837 x 10^-23 mL
<em>1pm=10^-12m</em>
<em>1cm=10^-2m</em>
<em>1mL=1cm^3</em>
<em></em>
density=mass/volume
density of V = 1.69x10^-22g÷2.837x10^-23mL
=5.957g/mL
=5.96g/cm^3
The answer is hyperbaric medicine.
Hyperbaric medicine is a treatment in which is necessary a chamber with
pressure greater than sea level atmospheric pressure. Is intended to reduce the effects of systemic gas bubbles by reducing their size and lead to their
elimination.
Answer:
15.9 grams of copper is produced
Explanation:
Step 1: Data given
Volume of hydrogen = 5.60 L ( at STP)
Step 2: The balanced equation
CuO (s) + H2 (g) → Cu (s) + H2O (g)
Step 3: Calculate moles H2
22.4 L = 1 mol
5.60 L = 0.25 moles
Step 3: Calculate moles Cu
For 1 mol CuO we need 1 mol H2 to produce 1 mol Cu and 1 mol H2O
For 0.25 moles H2 we'll have 0.25 moles Cu
Step 4: Calculate mass Cu
Mass Cu = moles Cu * molar mass Cu
Mass Cu = 0.25 moles * 63.546 g/mol
Mass Cu = 15.9 grams
15.9 grams of copper is produced
