The molar mass of M is  0.225g/mol and the element M is Hydrogen

If a metal M combines with an oxygen element to form the oxide, M_2O then the chemical reaction will be expressed as:

4M + O_2 -> 2M_2O\\

This shows that 4 moles of an unknown element M react with the oxygen element to produce the oxide M_2O

Given the following parameters

Mass of M = 0.890 grams

Mass of M_2O = 0.956 grams

Get the molar mass of M:

Molar mass = Mass/number of moles

Molar mass = 0.890/4

Molar mass = 0.225g/mol

Hence the molar mass of M is  0.225g/mol and the element M is Hydrogen

How many particles can be stored in a 4.0 L container at room temperature (23 C) and standard atmospheric pressure
velikii [3]

Answer: 9.91×10²³ particles

Explanation:

To find the amount of particles, you will need to use the Ideal Gas Law with what we are given.

Ideal Gas Law: PV=nRT

After we find moles, we can use Avogadro's number to convert to particles.

n=\frac{PV}{RT}

P=101.3kPa=1.00 atm

V=4.0 L

T=23°C+273.15=296.15 K

R=0.08206 Latm/Kmol

n=\frac{(1.00 atm)(4.0 L)}{(0.08206Latm/Kmol)(296.15K)}

n=0.164595 mol

Now that we have moles, we can convert to particles.

0.164595mol*\frac{6.022*10^2^3 particles}{mol} =9.91*10^2^2 particles
