5.60 g of an unknown gas at STP fills a 500 mL flask. What is the molar mass of the gas

ale4655 [162]

Hey there!

From ideal gas equation we know, PV = nRT

All the terms have their usual significance.

PV =w/M * RT

( where , n is number of moles = w/M, we = weight of gas, M = molecular weight of the gas)

Therefore, PV = wRT/M

At standard conditions , value of pressure, P = 1atm and standard temperature, T = 273K

And value of universal gas constant, R = 0.082 lit. atm. K⁻¹.mol⁻¹

Given that, weight of gas,

w = 5.60g and volume of gas,

V = 500mL = 0.5 Liters

Therefore, substituting all the value, we get :

Molar mass = 5.60 * 0.082 * 273 / 1 * 0.5

Molar mass = 250.7232 g/mole

Density of a piece of wood that has a measurement of 24 cm3 and 768 g

Brut [27]

Answer:

<h3>The answer is 32 g/cm³</h3>

Explanation:

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

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

From the question

mass = 768 g

volume = 24 cm³

We have

$density = \frac{768}{24} \\$

We have the final answer as

Hope this helps you
