Neon gas has a volume of 261 ml and a pressure of 108.5 kPa. What volume will the gas occupy at 96.5 kPa if the temperature rema

Tatiana [17]

Answer:

$\large \boxed{\text{293 mL}}$

Explanation:

The temperature and amount of gas are constant, so we can use Boyle’s Law.

$p_{1}V_{1} = p_{2}V_{2}$

Data:

$\begin{array}{rcrrcl}p_{1}& =& \text{108.5 kPa}\qquad & V_{1} &= & \text{261 mL} \\p_{2}& =& \text{96.5 kPa}\qquad & V_{2} &= & ?\\\end{array}$

Calculations:

$\begin{array}{rcl}108.5 \times 261 & =& 96.5V_{2}\\28320 & = & 96.5V_{2}\\V_{2} & = &\dfrac{28320}{96.5}\\\\& = &\textbf{293 mL}\\\end{array}\\\text{The volume of the gas is } \large \boxed{\textbf{293 mL}}$

Your solution has a volume of 36 ml and a mass of 970 g. what is the density of your solution

LenaWriter [7]

Answer:

The answer is

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass = 970 g

volume = 36 mL

The density of the object is

$density = \frac{970}{36} \\ 26.944444...$

We have the final answer as

Hope this helps you

Yasmin's teacher tells her that the solubility of salt is 360 g/L at room temperature (25 °C). How can Yasmin make an unsaturate

Bezzdna [24]

Answer:

By adding less amount or quantity of the salt (solute), than the medium (solvent) can dissolve at a particular temperature that is to make an unsaturated solution at room temperature, Yasmin should add less than 360 g of salt to one liter of the solvent

Explanation:

An unsaturated solution is one that consists of less than the maximum mass or quantity of the solute that it is capable of dissolving.
