Answer : The molar mass of unknown gas is, 41 g/mole
Solution : Given,
Diffusion rate of neon gas = 7 cm/s
Diffusion rate of unknown gas = 4.9 cm/s
Molar mass of neon gas = 20 g/mole
According to the Graham's law, the rate of effusion of a gas is inversely proportional to the square root of the molar mass of the gas.
Formula used :
where,
= diffusion rate of neon gas
= diffusion rate of unknown gas
= molar mass of neon gas
= molar mass of unknown gas
Now put all the given values in the above formula, we get the molar mass of unknown gas.
Therefore, the molar mass of unknown gas is, 41 g/mole
a because as temperature increases, reaction rate increases.
The plant will grow towards the light source.
Answer:
7.1 moles Cl₂
Explanation:
To solve this problem we will use <em>Avogadro's number </em>(Aₙ), which tells us how many molecules (or atoms) are present in 1 mol of any given substance
Aₙ = 6.023 x 10²³ molecules/mol
With that in mind now we proceed to convert molecules into moles:
4.28 x 10²⁴ molecules Cl₂ ÷ 6.023 x 10²³ molecules/mol = 7.1 moles Cl₂
Answer:
Gamma Ray's have the highest frequency.
