What is the molar mass of HBR
alexdok [17]

Answer:

Molar mass of bromine is equal to 80.9119

Explanation:

The molar mass of HBr is equal to the sum of atomic weight of  Bromine.

Atomic Weight of hydrogen is equal to 1.00794

Atomic Weight  of Bromine is equal to 79.904

Molar mass of Bromine

= Atomic Weight of hydrogen + Atomic Weight  of Bromine

Molar mass of Bromine  = 79.904 + 1.00794  = 80.9119

A stock bottle of an acid reads: 56% by mass and 1.25 specific gravity. If the molar mass of the acid is 70g, find the mole per
TiliK225 [7]

Answer:

  • <u>10 mol / dm³</u>

Explanation:

Cubic decimeter is the same unit as liter; so, mole per cubic decimeter is mole per liter, and that is the unit of concentration of molarity. Thus, what is asked is the molarity of the solution. This is how you find it.

1. <u>Take a basis</u>: 1 dm³ = 1 liter = 1,000 ml

2. <u>Calculate the mass of 1 lite</u>r (1,000 ml) of solution:

  • density = mass / volume ⇒ mass = density × volume

Here, the density is given through the specific gravity

Scpecific gravity = density of acid / density of water

Take density of water as 1.00 g/ml.

  • density of solution = 1.25 g/ml

  • mass solution = 1.25 g/ml × 1,000 ml = 1,250 g

3. <u>Calculate the mass of solute</u> (pure acid)

  • % m/m = (mass of solute / mass of solution) × 100

  • 56 = mass of solute / 1,250 g × 100

  • mass of solute = 56 × 1,250g / 100 = 700 g

4. <u>Calculate the number of moles of solute</u>:

  • moles = mass in grams / molar mass = 700 g / 70 g/mol = 10 mol

5. <u>Calculate molarity (mol / dm³)</u>

  • M = number of moles of solute / liter of solution = 10 mol / 1 liter = 10 mol/liter.

Magnetite is a binary compound containing only iron and oxygen. the percent, by weight, of iron is 72.360%. what is the empirica
hram777 [196]
Answer is: <span>c. Fe</span>₃<span>O</span>₄<span>.
</span>ω(Fe) = 72,360%.
ω(O) = 100% - 72,36% = 27,64%.
For example, if we the mass of compound is 100 g:
m(Fe) = 72,36 g.
n(Fe) = m(Fe) ÷ M(Fe).
n(Fe) = 72,36 g ÷ 55,85 g/mol.
n(Fe) = 1,296 mol.
n(O) = 27,64 g ÷ 16 g/mol.
n(O) = 1,727 mol.
n(Fe) : n(O) = 1,296 mol : 1,727 mol.
n(Fe) : n(O) = 1 : 1,33 or 3 : 4.
