What is the density (in g/L) of a gas with a molar mass of 16.01 g/mol at 1.75 ATM and 337 K?

To solve for density, you can use the formula--> Density= PM/ RT, where P stands for pressure, M for molar mass, R represents the gas constant, and T is temperature.

P= 1.75 atm
M= 16.01 g/ mol
R= 0.0821 atm·L/ mol·K
T=337 k

Thus, the density calculation becomes: density= (1.75 x 16.01)/ (0.0821 x 337)= 1.01 g/L

Response: The density of the gas is 1.013 g/L

Solution: Given,

The molar mass of the gas = 16.01 g/mole

Gas pressure = 1.75 atm

Gas temperature = 337 K

Utilizing the ideal gas law equation,

$PV=nRT$

$PV=\frac{w}{M}\times RT\\\\P=\frac{w}{V}\times \frac{RT}{M}\\\\P=\rho\times \frac{RT}{M}\\\\\rho=\frac{PM}{RT}$

We know that $Density=\frac{Mass}{Volume}$

where,

P = pressure of the gas

V = volume of the gas

T = temperature of the gas

n = number of moles of the gas

w = mass of gas

M = molar mass of the gas

R = gas constant = 0.0821 Latm/moleK

$\rho$ = density of gas

Next, by inserting all known values into the formula, we determine the gas density.

$\rho=\frac{PM}{RT}$

$\rho=\frac{(1.75atm)\times (16.01g/mole)}{(0.0821Latm/moleK)\times (337K)}=1.013L$

Thus, the gas density is 1.013 g/L

Step $1$ : To find the mass of a single washer, divide the total measured mass by the number of washers $\frac{0.4168}{1000} =0.0004168\ Kg$ $0.0004168kg=4.168*10^{-4} kg$ . Step $2$ : Convert kilograms to milligrams knowing $1 kg=1*10^{6} mg$ ; thus $4.168*10^{-4}*10^{6} =4.168*10^{2}mg=416.8 mg$ resulting in the final answer $416.8 mg$ .

Answer:

0.31%

Explanation:

For the chemical reaction:

I₂ + 2 S₂O₃²⁻ → 2 I⁻ + S₄O₆²⁻

0.043 L multiplied by 0.117 M of sodium thiosulfate gives 5.031x10⁻³ moles of S₂O₃²⁻

5.031x10⁻³ moles of S₂O₃²⁻ produces:

ClO⁻⁻ + 2 H⁺ + 2 I⁻ → I₂ + Cl⁻ + H2O

2.5156x10⁻³ moles of I₂ equates to moles of NaClO

2.5156x10⁻³ moles of NaClO times $\frac{74,44 g}{1mol}$ yields 0.187 g of NaClO

Thus, the mass percentage composition is:

$\frac{0,187 g of NaClO}{60 g Of Bleach} x 100$ = 0.31%

I hope this helps!

Response:

Explanation:

Stearic acid - C18H36O2

Fructose- C6H12O6

The energy content in food is largely proportional to the carbon content. This can be expressed as:

C18/C6 = 3 or 3:1

This illustrates why fats and oils serve as the primary energy source for the body rather than carbohydrates. This is because fats and oils contain significantly higher amounts of carbon compared to carbohydrates.
