Data Given:
Pressure = P = 2.5 kPa = 0.02467 atm
Temperature = T = 157 °C + 273.15 = 430.15 K
Volume = V = ?
Mass = m = 10 g
First find out moles for given amount of Argon gas,
As,
Moles = Mass / M.mass
Putting values,
Moles = 10 g / 39.94 g/mol = 0.250 moles
Now using Ideal Gas Equation,
P V = n R T
Solving for V,
V = n R T / P
Putting Values,
V = (0.25 mol × 0.0821 L.atm.mol⁻¹.K⁻¹ × 430.15 K) ÷ 0.02467 atm
Volume = 357.87 L
that's instrument picture there is an manometer
Answer:
6.0×10_10=50 I hope I'm right
78 and 78. An atom of the element has 78 electrons and 78 protons.
The atomic number is 78, so the atom has 78 protons (+).
If the atom is neutral, it must contain 78 electrons (-).
Answer:
Explanation:
Hello there!
In this case, according to the given information and the chemical reaction, whereby iron and hydrochloric acid react in a 1:2 mole ratio, it is firstly necessary to calculate the moles of iron (II) chloride from each reactant in order to figure out the limiting reactant:
In such a way, we infer the maximum moles of FeCl2 product are yielded by HCl, for which it is the limiting reactant. Finally, we calculate the grams of product by using its molar mass as shown below:
