Answer:
23.76g
Explanation:
To solve for the mass of carbon dioxide (CO2), let us first obtain the number of mole of CO2.
From the question, the following were obtained:
V = 8.13L
P = 204kPa = 204000Pa
Recall: 101325Pa = 1atm
204000Pa = 204000/101325 = 2atm
T = 95°C = 95 + 273 = 368K
R = 0.082atm.L/K/mol
n =?
PV = nRT
n = PV /RT
n = 2 x 8.13/ 0.082 x 368
n = 0.54mole
Now let us convert 0.54mole of CO2 to gram. This is illustrated below:
Molar Mass of CO2 = 12 + (16x2) = 12 + 32 = 44g/mol
Number of mole of CO2 = 0.54mole
Mass of CO2 =?
Number of mole = Mass /Molar Mass
Mass = number of mole x molar Mass
Mass of CO2 = 0.54 x 44
Mass of CO2 = 23.76g
Sodium, potassium, strontium, calcium, and magnesium
Answer:
2.82 * 10^-25 g
Explanation:
Given that :
Atomic number = 17
Mass of an atom of the element =?
Avogadro's constant = 6.022 * 10^23
The mass of an atom. Of the element is :
Atomic mass / Avogadro's constant
= 17 / 6.022 * 10^23
= 2.82 * 10^-25
=
Answer:
<h3>The answer is 3.0 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 15 g
volume = 5 mL
We have
We have the final answer as
<h3>3.0 g/mL</h3>
Hope this helps you
well it is most commonly found at the absolute highest point or the absoulute lowest! so it is seen to have occured at these 2 points...
1.(lowest) 400-500 400!
2.(highest) 400-500 400!
<em>I hope this helps you!</em>
