What’s the density if the mass is 40.8g and the volume is 60mL?
luda_lava [24]

Answer:

We have the final answer as

<h2>0.68 g/mL</h2>

Explanation:

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

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

From the question

mass = 40.8 g

volume = 60 mL

The density is

density =  \frac{40.8}{60}  \\

We have the final answer as

<h3>0.68 g/mL</h3>

Hope this helps you

Question 6: The Ideal Gas Law (7 points) a. What is the mathematical equation for the ideal gas law? Identify each variable and
azamat

The mathematical equation for the ideal gas law is PV = nRT.

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

(A)

PV = nRT

The ideal gas equation is formulated as: PV = nRT. In this equation, P refers to the pressure of the ideal gas, V is the volume of the ideal gas, n is the total amount of ideal gas that is measured in terms of moles, R is the universal gas constant, and T is the temperature.

(B)

Where the pressure - P, is in atmospheres (atm) the volume - V, is in liters (L) the moles -n, are in moles (m) and Temperature -T is in Kelvin (K) as in all gas law calculations.

(C)

A. Boyle's law

B. Charles's law

C. Avogadro's law

D. Dalton's law

____ - P_1V_1 = P_2 V_2

____ \frac{V}{T} = k

____ \frac{V_1}{T_1} = \frac{V_2}{T_2}

____ V = kn

____ PV = k

____- P total = P_1 + P_2 + P_3 + ...

<u>Boyle's</u><u> law</u> - P_1V_1 = P_2 V_2

<u>Charles's</u><u> law</u> - \frac{V}{T} = K

<u>Charles's law</u> - \frac{V_1}{T_1} = \frac{V_2}{T_2}

<u>Avogadro's law</u>- V = kn

<u>Boyle's law</u> - PV = k

<u>Dalton's law</u><u> </u>- P total = P_1 + P_2 + P_3 + ...
