The question is incomplete, here is the complete question:

Gaseous compound Q contains only xenon and oxygen. When a 0.100 g sample of Q is placed in a 50.0-mL steel vessel at 0°C, the pressure is 0.229 atm. What is the likely formula of the compound?

A. XeO

B. $XeO_4$

C. $Xe_2O_2$

D. $Xe_2O_3$

E. $Xe_3O_2$

<u>Answer:</u> The chemical formula of the compound is $XeO_4$

<u>Explanation:</u>

To calculate the molecular mass of the compound, we use the equation given by ideal gas equation:

PV = nRT

Or,

$PV=\frac{w}{M}RT$

where,

P = Pressure of the gas = 0.229 atm

V = Volume of the gas = 50.0 mL = 0.050 L (Conversion factor: 1 L = 1000 mL)

w = Weight of the gas = 0.100 g

M = Molar mass of gas = ?

R = Gas constant = $0.0821\text{ L atm }mol^{-1}K^{-1}$

T = Temperature of the gas = $0^oC=273K$

Putting value in above equation, we get:

$0.229\times 0.050=\frac{0.100}{M}\times 0.0821\times 273\\\\M=\frac{0.100\times 0.0821\times 273}{0.229\times 0.050}=195.4g/mol\approx 195g/mol$

The compound having mass as 195 g/mol is $XeO_4$

Hence, the chemical formula of the compound is $XeO_4$

What is the volume (in cubic inches) of 3.8 lb of titanium?

makkiz [27]

Given the mass of Titanium = 3.8 lb

Density of Titanium is 4.506 $\frac{g}{cm^{3} }$

We can calculate the volume of Titanium using density and mass.

Converting mass from lb to g:

$3.8lb *\frac{453.6 g}{1 lb} = 1724 g$

Calculating the volume of Titanium using density and mass:

$1724 g * \frac{cm^{3} }{4.506g} =382.6 cm^{3}$

Converting volume from $cm^{3} to in^{3}$ :

$382.6 cm^{3} * \frac{ 1 in^{3} }{16.39cm^{3} } = 23.34 in^{3}$

A solution is made by dissolving 0.611 mol of NaCl in 250 g of water. If the molar mass of NaCl is 58.44 g/mol, what is the mola

shusha [124]

Molality= moles NaCl/ Kg H2O

250 g (1 Kg/ 1000 grams)= 0.250 Kg

Molality= 0.611 moles/ 0.250 Kg= 2.44 molal
