Answer:

The volume inside the balloon is = 121 m^{3}

Explanation:

Temperature T = - 1 °c = 272 K

Pressure = 0.7 atm = 71 k pa

No. of moles = 3.8

Mass of the gas inside the volume = 3.8 × 4 = 15.2 kg

From ideal gas equation

P V = m R T

Put all the values in above formula we get

71 × V =15.2 × 2.077 × 272

V = 121 m^{3}

Therefore the volume inside the balloon is = 121 m^{3}

Answer:

\large \boxed{\text{121 L}}

Explanation:

We can use the Ideal Gas Law.

pV = nRT

Data:

p = 0.700 atm

n = 3.80 mol

T = -1  °C

Calculations:

1. Convert the temperature to kelvins

T = (-1 + 273.15) K= 272.15 K

2. Calculate the volume

\begin{array}{rcl}pV &=& nRT\\\text{0.700 atm} \times V & = & \text{3.80 mol} \times \text{0.082 06 L}\cdot\text{atm}\cdot\text{K}^{-1}\text{mol}^{-1} \times \text{272.15 K}\\0.700V & = & \text{84.86 L}\\V & = & \textbf{121 L} \\\end{array}\\\text{The volume of the balloon is $\large \boxed{\textbf{121 L}}$}

A compound is found to contain 50. 05% sulfur and 49. 95% oxygen by mass. What is the empirical formula for this compound? SO S2
jekas [21]

The empirical formula for the given compound has been \rm SO_2. Thus, option C is correct.

The empirical formula has been the whole unit ratio of the elements in the formula unit.

<h3>Computation for the Empirical formula</h3>

The given mass of Sulfur has been, 50.05 g

The given mass of oxygen has been 49.95 g.

The moles of elements in the sample has been given by:

\rm Moles=\dfrac{Mass}{Molar\;mass}

  • Moles of Sulfur:

\rm Moles\;S=\dfrac{50.05}{32}\\&#10; Moles\;S=1.56\;mol

The moles of sulfur in the unit has been 1.56 mol.

  • Moles of Oxygen:

\rm Moles\;O=\dfrac{49.95}{16} \\&#10;Moles\;O=3.12\;mol

The moles of oxygen in the unit has been 3.12 mol.

The empirical formula unit has been given as:

\rm S_{1.56}O_{3.12}=SO_2

Thus, the empirical formula for the given compound has been \rm SO_2. Thus, option C is correct.

Find [cu2+] in a solution saturated with cu4(oh)6(so4) if [oh − ] is fixed at 2.3 ✕ 10−6 m. note that cu4(oh)6(so4) gives 1 mol

You have OH-  conc = </span>2.3 ✕ 10−6 m
From the formula, you can observe the ratio of Cu2+ to OH- is  4 : 6 = 2:3

So, for 2.3 ✕ 10−6 m OH-
[Cu2+] = \frac{2}{3} \times 2.3 \times 10^{-6}

= 1.53  \times 10^{-6} &#10;

recheck Fusion reactions power the in space. Humans currently use fusion in , but researchers are seeking more applications.
quester [9]

One: looks to be correct for both answers. Certainly the first one is. The second depends on your other choices. But military use is one.

Two: is correct. Pd has (in this case) an atomic mass of 114 and its number is 46

Three: Even with my slop numbers, 4.98  is the answer (although I get 4.99 but again, my numbers are pretty sloppy).

Four: Slop numbers say 78.3, but 78 is the right answer.

Five: Slop numbers agree with Al2S3. I think that's D

They are all correct. Very Fine Work.
