The amount of moles in 3.34 x10³⁴ formula unit of Cu(OH)₂ is 5.55 × 10¹⁰ moles
<u><em>calculation</em></u>
The amount of moles is calculated using the Avogadro's law constant
That is 1 moles = 6.02 × 10²³ formula units
? moles = 3.34 × 10³⁴ formula units
<em>by cross multiplication</em>
= {1 mole ×3.34 ×10³⁴ formula units ] / 6.02 × 10²³ formula units} = 5.55 ×10¹⁰ moles
Answer: F<em>or the volume of gas changes from 5L to 3L, what will be the new pressure? What law did you use and why</em>
<em>For example, if you want to calculate the volume of 40 moles of a gas under a pressure of 1013 hPa and at a temperature of 250 K, the result will be equal to: V = nRT/p = 40 * 8.3144598 * 250 / 101300 = 0.82 m³</em>

Answer: 83.74L
Explanation:
Temp. = 295K
P = 713torr = 0.938atm
Mass = 2.65g
PV = nRT
V = nRT/PV
n = Mass/Molar mass
Molar mass of Hydrogen gas = 1.00784*2= 2.0156g/mok
n = 2.65/2.0156 = 1.31469mol
V = 1.31469*0.08205*295/0.938
V = 83.74L
The volume = 83.74L
Answer:
Environment: They must be supplied and used in ways that have minimal safety and environmental stewardship have advanced safety regulations and practices, promulgated rules for reducing VOC emissions from oil and gas production and ... disposal protocols are similarly reducing negative impacts to air and water.
