Explanation:
it is a trench so if they went together then they would rise up but if they missed then it would create a hole
The noble gas is Xenon and its molar mass is 131 g/mol.
<h3>What is the molar mass of the noble gas?</h3>
The molar mass of the noble gas is determined as follows;
Let molar mass of unknown gas be M, and mass of gas be m
Density of the noble gas, ρ = 5.8 g/dm³
density = m/V
At STP;
- temperature, T = 273.15 K
- pressure, P = 1 atm
- molar gas constant, R = 0.0821 L.atmK⁻¹mol⁻¹
From ideal gas equation:
PV = nRT
where n = m/M
PV = mRT/M
M = mRT/PV
M = 0.0821 * 273.15 * 5.84/1
Molar mass of the noble gas = 131 g/mol
The noble gas is Xenon which has molar mass approximately equal to 131 g/mol.

Answer:
Explanation:
Boyle believed that chemistry – the behavior of substances – could be explained through the motion of atoms, which in turn could be understood through mechanics – Galileo's mathematics of motion. Boyle was ultimately proved correct, because today we can understand chemistry mathematically, through quantum mechanics.
The accepted value was either 3.10 g or 3.20 g
Why?
There are two possibilities:
- The <em>accepted value</em> is lower than the <em>experimental value</em> by 1.61%
- The <em>accepted value</em> is higher than the<em> experimental value</em> by 1.61%
The formula for the percent error is the following:
Clearing for Accepted Value and inputting the values we get the following:
Another possibility is that the the Accepted value is <em>higher</em>. In that case we'd get:
.
The <em>most likely</em> value for the accepted value is 3.20 g, as most experiments in which mass is recovered yield a lower experimental value than the initial one.
Have a nice day!
