Congratulations! You’ve recently received a promotion from work. Your new job is to fill rooms with certain gases. A room is fou

nd to measure 9.00 feet wide by 12.0 feet long and 10.0 feet high. Your first assignment is to fill this room with a gas that has a density of 0.88543 kg/m3. Unfortunately your boss is asking you to make the gas (if you know what I mean). How many grams of this gas are required to fill the room? (1m3 = 35.3147 ft3) (Round to the appropriate sig fig)

The amount of gas required to fill the room is 27076.4 g

To calculate the grams of the gas that will fill the room, we make use of the formula below

⇒ Formula:

  • D = m/V....................... Equation 1

⇒ Where:

  • D = Density of the gas
  • m = mass of the gas
  • V = Volume of the room

⇒ make m the subject of the equation

  • m = DV................... Equation 2

From the question,

⇒ Given:

  • D = 0.88543 kg/m³
  • V = Volume of a cubiod = Length×Width×Height = 9×12×10 = 1080 ft³

⇒ Converting the volume from ft³ to m³

  • V = 1080/35.3147
  • V = 30.58 m³

Substitute these values into equation 2

  • m = 0.88543(30.58)
  • m = 27.0764 kg
  • m ≈ 27076.4 g

Hence, The amount of gas required to fill the room is 27076.4 g

2. What is the mass of 5.33 x 10 moles of aluminum hydroxide?​
bearhunter [10]
<h3>Answer:</h3><h3>1865.5g</h3><h3>Explanation:</h3><h3 /><h2> first the chemical formular for ammonium hydroxide is NH4OH</h2><h3>its molarmass is given as N=14H=1O=16 </h3><h3> so we have 14 +1(2) +16+1 =35</h3><h2>also no of moles = mass / molarmass</h2><h3> we have 5.33×10 = mass/35 </h3><h2>therefore mass = 35 ×5.33×10 = 1865.5g</h2>

1. An atom of an elephant has atomic mass of 39 and has number of neutrons as 20 calculate protons number.
r-ruslan [8.4K]

Answer:

See Explanation

Explanation:

1) Let us recall that;

Mass number = number of protons + number of neutrons

Where;

Number of protons = ?

Number of neutrons =20

Mass number =39

Number of protons = mass number - number of neutrons

Mass of protons =39 - 20= 19 protons

2) Atomic number = 13

Number of neutrons =14

Then the mass number =13 +14 =27

The symbol of the element is 27X13

The number of protons= the number of electrons =13

The atomic number is the same as the proton number =13

A chemist adds of a calcium sulfate solution to a reaction flask. Calculate the mass in grams of calcium sulfate the chemist has
Elanso [62]

The given question is incomplete. The complete question is:

A chemist adds 0.85 L of a 0.0050M calcium sulfate to a reaction flask. Calculate the mass in grams of calcium sulfate the chemist has added to the flask. Round your answer to significant digits.

Answer: The mass in grams of calcium sulfate the chemist has added to the flask is 0.58 g

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n}{V_s}

where,

n = moles of solute

V_s = volume of solution in L

moles of CaSO_4 = \frac{\text {given mass}}{\text {Molar mass}}=\frac{xg}{136g/mol}

Now put all the given values in the formula of molarity, we get

0.0050=\frac{x}{136\times 0.85}

x=0.58 g

Therefore, the mass in grams of calcium sulfate the chemist has added to the flask is 0.58 g
