How many moles of atoms are contained in the following 2.25g of k

Chemistry
1 answer:
ZanzabumX [31]3 years ago
8 0
Atomic mass (K)= 39.1 amu

therefore:
1 mol (k)---------------------39.1 g
x------------------------------- 2.25 g

x=(1 mol * 2.25 g) / 39.1 g=0.05754....≈0.06 moles

Answer: 0.06 moles.

What is the relationship between Celsius and kelvin
Inga [223]

The relationship between Celsius and kelvin is that degrees Kelvin is equal to degrees Celsius + 273.15. That means that the freezing point of water (0°C) is 273.15° kelvin. This makes an additive relationship between the two quantities, so quantities such as the boiling point and freezing point of water are the same distance apart on the Kelvin scale (100 degrees). This means that kelvin has the same magnitude as Celsius.

When the pressure that a gas exerts on a sealed container changes from 22.5 psi to ? psi, the temperature changes from 110 degre
natta225 [31]
Using Gay-Lussac's Law, pressure is proportional to (absolute) temperature in Kelvin. We first convert the temperature values to Kelvin: 110 C = 383.15 K, while 65 C = 338.15 K.
P1/T1 = P2/T2
22.5/383.15 = P2/338.15
P2 = 19.9 psi

Acetone major species present when dissolved in water
jek_recluse [69]

Answer: acetone molecule ( CH₃-CO-CH₃)


Explanation:


1) Acetone is CH₃-CO-CH₃


2) That is a molecule (build up of covalent bonds).


3) When dissolved, covalent bonded compounds remain as separate molecules, then it is said that the major species present in the solution is the molecule. The molecules of acetone are surrounded (sovated) by the molecules of water.


This as opposed to the case of ionic compounds that ionize. When a compound as NaCl dissolves in water, it ionizes completely, so the major speceies are not NaCl formulas, but the ions Na⁺ and Cl⁻, not molecules.


That leads to the answer: the major species present when acetone is dissolved in water is the molecules of acetone (you do not need to state the fact that the molecules of water are part of the solution, because that is not the target of the question).
