Answer: radon (atomic mass 222 amu
Explanation:
To calculate the rate of diffusion of gas, we use Graham's Law.
This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows:
atomic mass of krypton= 83.8 amu
atomic mass of argon= 39.95 amu
atomic mass of xenon = 131.3 amu
atomic mass of radon= 222 amu
Thus as atomic mass of radon is highest, its rate of diffusion is slowest.
Answer:
0.500 mol/dm³
Explanation:
Using the formula below;
CaVa = CbVb
Where;
Ca = concentration of acid (mol/dm³)
Cb = concentration of base (mol/dm³)
Va = volume of acid (cm³)
Vb = volume of base (cm³)
In accordance to the information provided in this question is;
Va = 5cm³
Vb = 250 cm³
Ca = 12 mol/dm³
Cb = ?
Using CaVa = CbVb
12 × 5 = Cb × 250
60 = 120Cb
Cb = 60/120
Cb = 0.500 mol/dm³
You just need to convert it into moles per Liter (mol/L).
0.0815mol / 0.550L = 0.148mol/L
TRUE its glucose if they have sunlight
Is there an attachment because it depends on the element.
