The ratio of the diffusion rates of two gases is given by the formula r1/r2=square root m2/square root m1 wherem1 and m2 are the masses of the molecules of the gases. find r1/r2 if m1=12 units and m2=30 units. your answer should be in simplified radical form
what is answer
12 squared divided by 30 squared is 5/2
therefore r1/r2 = 5/2
the answer is B. 10/2 which can be simplified to 5/2
The awnser is B: 10/2 lol
the answer is the root of 10 over 2 because the problem says to put the root of 30 over the root of 12 and that gives you the root of 10 over 2. You're welcome hopefully this is right for everybody

To find the ratio r1/r2, we need to substitute the given values of m1 and m2 into the formula and simplify the expression.
Given:
m1 = 12 units
m2 = 30 units
The formula for the ratio r1/r2 is:
r1/r2 = √(m2) / √(m1)
Substituting the values of m1 and m2:
r1/r2 = √(30) / √(12)
To simplify the expression, we can simplify the individual square roots first.
√(30) can be written as √(6*5), and since 6 and 5 do not have any perfect square factors, we cannot simplify it further.
√(12) can be written as √(4*3), and √4 is equal to 2 because 2² = 4. So, √(12) simplifies to 2√(3).
Plugging these values back into the formula:
r1/r2 = (√(30)) / (√(12))
= (√(6*5)) / (2√3)
Next, we can simplify the expression by dividing the square roots:
r1/r2 = (√(6*5)) / (2√3)
= (√6 * √5) / (2 * √3)
Since there is no common factor between the numerator and denominator, we cannot simplify it any further.
Thus, the ratio r1/r2, in simplified radical form, is (√6 * √5) / (2 * √3).
