Answer:
[H₂SO₄] = 6.07 M
Explanation:
Analyse the data given
8.01 m → 8.01 moles of solute in 1kg of solvent.
1.354 g/mL → Solution density
We convert the moles of solute to mass → 8.01 mol . 98g /1mol = 785.4 g
Mass of solvent = 1kg = 1000 g
Mass of solution = 1000g + 785.4 g = 1785.4 g
We apply density to determine the volume of solution
Density = Mass / volume → Volume = mass / density
1785.4 g / 1.354 g/mL = 1318.6 mL
We need this volume in L, in order to reach molarity:
1318.6 mL . 1L / 1000mL = 1.3186 L ≅ 1.32L
Molarity (mol/L) → 8.01 mol / 1.32L = 6.07M
Answer:
CaF2
Explanation:
1 mole of CaF2 = 78.0748064 grams
78 times 3.33= 259.74
the others multiplied were nowhere near 260 grams either
Vapor pressure of a liquid increases with increasing temperature because increasing the temperature results in increasing kinetic energy and increase in molecular transition and motion.
What is Vapor Pressure?
- The pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a specific temperature in a closed system is referred to as vapor pressure.
- A liquid's evaporation rate can be determined by looking at the equilibrium vapor pressure. It has to do with how often particles tend to float away from liquids (or a solid).
- Volatile is a term used to describe a chemical that has a high vapor pressure at room temperature. Vapor pressure is the force that vapor exerts when it is present above a liquid surface.
- A liquid's molecules have an increasing kinetic energy as its temperature rises. The more molecules that convert into a vapor as a result of an increase in molecular kinetic energy, the higher the vapor pressure will be.
