Amorphous solids have two characteristic properties. When cleaved or broken, they produce fragments with irregular, often curved surfaces; and they have poorly defined patterns when exposed to x-rays because their components are not arranged in a regular array. An amorphous, translucent solid is called a glass

What volume is occupied by 2.0 mol of gas at 3.0 atm<br> and 27 °C?
Oduvanchick [21]
STP conditions imply a temperature of 273.15 K and a pressure of 100 kPa. When tose conditions are met, 1 mole of any ideal gas will have a volume of 22.7 L. So, if 1 mole occupies a volume of 22.7 L, 2 moles will occupy a volume twice as big. Likewise, 0.5 moles will occupy half the volume 1 mole occupies.

2. If 1.75 L of a gas is at 700. K and is under 250. kPa of pressure, what will the new
Andrews [41]

Answer:

Final volume is 3.50L

Explanation:

It is possible to find volume of a gas using combined gas law:

\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}

<em>Where P is pressure, V is volume and T is temperature of 1: initial state and 2: final state</em>

If initial state of the gas is:

1.75L of a gas is at 700K and is under 250kPa of pressure

And final state is:

298K and 53.2kPa.

Replacing:

\frac{250kPa*1.75L}{700K} =\frac{53.2kPa*V_2}{298K}

0.625L = 0.1785*V₂

<em>3.50L = V₂</em>

Thus, <em>final volume is 3.50L</em>

How many moles of NO2 are equivlent to 74.3 grams of NO2N=14.01/ o=16.00?
lesantik [10]

The molecular mass of HNO_2 is: 1·1 + 1·14.01 + 2·16 = 47.01 g/mol.


Now we can convert the mass into mol of HNO_2:


74.3\ g\ HNO_2\cdot \frac{1\ mol}{47\ g} = \bf 1,58\ mol\ HNO_2
