How many liters do 1.55 g of O2 occupy at STP?

Chemistry
1 answer:

3 0

The volume that is occupied by the given mass of the oxygen gas is 1.1L

<h3>What is the volume?</h3>

We know that the volume has to do with the space that is occupied by a gas. Now we know that from the Avogadro's law, the volume that is occupied by a gas is called the molar volume of the gas and it has a value of 22.4 L.

We now have;

Number of moles of the gas = 1.55 g/32 g/mol

= 0.048 moles

If 1 mole of the gas occupies 22.4 L

0.048 moles of the gas is going to occupy 0.048 moles * 22.4 L/1 mole

= 1.1 L

Silver bromide (AgBr) has a solubility of 7.07 × 10^-7 mol/L
kirill115 [55]

a. AgBr(s)⇒ Ag⁺(aq) + Br⁻(aq)

b.  Ksp AgBr = s²

c. 5 x 10⁻¹³  mol/L

<h3>Further explanation</h3>

Given

solubility AgBr = 7.07 x 10⁻⁷ mol/L

Required

The dissolution reaction

Ksp

The solubility product constant

Solution

a. dissolution reaction of AgBr

AgBr(s)⇒ Ag⁺(aq) + Br⁻(aq)

b. Ksp

Ksp AgBr  = [Ag⁺]  [Br⁻]

Ksp AgBr = (s) (s)

Ksp AgBr = s²

c. Ksp AgBr = (7.07 x 10⁻⁷)² = 5 x 10⁻¹³  mol/L

elena55 [62]

7.93 x 10⁶mi

Explanation:

Significant figures are numbers that shows how accurate and precise scientific measurements are reported.

Here are some rules to identifying them;

  • All non-zero digits are significant
  • zeros between digits are significant
  • leading zero before a decimal are not significant
  • trailing zero after a decimal are significant
  • trailing zero before a decimal point are significant.

The number 7926381  has 7 significant numbers.

To write in the scientific notation, we simply express as N x 10ᵃ

   N is the number of significant number

   a is the exponent

N here is 7.93

a here is 6

            7.93 x 10⁶mi
