Answer: The molarity of this solution is 0.159 M.
Explanation:
Given: Mass of solute = 16.3 g
Volume = 1.75 L
Number of moles is defined as the mass of substance divided by its molar mass.
Hence, moles of NaCl (molar mass = 58.44 g/mol) ar calculated as follows.
Molarity is the number of moles of a substance present in a liter of solution.
So, molarity of the given solution is calculated as follows.
Thus, we can conclude that the molarity of this solution is 0.159 M.

Explanation:
There are many properties that scientists use to describe waves. They include amplitude, frequency, period, wavelength, speed, and phase. Each of these properties is described in more detail below. When drawing a wave or looking at a wave on a graph, we draw the wave as a snapshot in time.
Answer: Number of atoms in 
of radon gas (radon atoms) at the same temperature and pressure is 
Explanation:
According to avogadro's law, volume of a gas is directly proportional to the number of moles present when temperature and pressure is constant.:
= moles of hydrogen gas = 
= moles of radon gas = ?
Thus the number of atoms in of radon gas (radon atoms) at the same temperature and pressure is
