The volume of the sample of propane at STP is 0.62 mL.

<h3>What is volume?</h3>

Volume is the amount of space that a substance or object occupies.

To calculate the volume of gas at STP, we apply the formula below.

Formula:

  • PV/T = P'V'/T'................. Equation 1

Where:

  • P = Initial pressure of gas
  • V = Initial volume of gas
  • T = Initial temperature of gas
  • P' = Standard pressure (SP)
  • T' = Standard temperature (ST)
  • V' = Volume of gas at STP.

Make V' The subject of the equation

  • V' = PVT'/P'T.............. Equation 2

From the question,

Given:

  • P = 320 torr
  • V = 1.73 mL
  • T = 30 °C = (30+273) K = 303 K
  • P' = 760 torr
  • T' = 273 K

Substitute these values into equation 2

  • V' = (320×1.73×273)/(760×303)
  • V' = 0.62 mL

Hence, the volume of the sample of propane at STP is 0.62 mL.

Identify the compound that would have the highest osmotic pressure when dissolved in water. nacl k2so4 mgcl2 fecl3 mgso4
brilliants [131]

The compound that would have the highest osmotic pressure when dissolved in water is FeCl_{3} .

So,  option D is correct one.

The dissociation of one molecule of  FeCl_{3} gives the maximum number of ions when dissolved in water ( 4 ions ) . Osmotic pressure is a colligative property and depends upon number of solute particles present in the solution . The solution having maximum number of solute particles will have maximum number of the osmotic pressure .

All other given molecules gives less number of number of ions when dissolved in water as compare to of  FeCl_{3} .

Which element does this Bohr model represent? (look at a periodic table if needed)
Serjik [45]
Circulating round the nucleus are the electrons in various orbits of different energy levels. Electrons are negatively charged and represented by the symbol 'e'. In the given image the number of protons are -6. Hence the element in question is Carbon as Carbon has the atomic number 6.
