Answer:
The mass of 0.100 mole of neon is 2.018 grams.
Explanation:
As we know the formula to find mass:
Number of moles = Mass/ Molar mass
0.100 = Mass/ 20.17
0.100 x 20.17 = Mass
Mass=2.018 grams.
Hope it helps!
If you keep an egg in salt for too long.....it might form a stronger shell because salt helps fill up the cracks....but I have no idea. =\
It is the lowest whole number ratio of ions represented in an ionic compound. Examples include ionic NaCl and K2O and covalent networks such as SiO2<span> and C (as diamond or graphite). Ionic </span>compounds<span> do not exist as individual molecules; a </span>formula unit<span> thus indicates the lowest reduced ratio of ions in the </span>compound<span>.</span>
Answer:
V₂ = 530.5 mL
Explanation:
Given data:
Initial temperature = 20.0°C
Final temperature = 40.0 °C
Final volume = 585 mL
Initial volume = ?
Solution:
Initial temperature = 20.0°C (20+273 = 293 K)
Final temperature = 40.0 °C (40+273 = 323 K)
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₁ = V₂T₁ /T₂
V₂ = 585 mL × 293 K / 323 K
V₂ = 171405 mL.K / 323 K
V₂ = 530.5 mL
