Answer 2

Given Information:

- m3 = 300 g - W3 = 12% - W1 = 26% - W2 = 8%

Finding m1 and m2:

To find m1 and m2, we need to use the concept of mass percent composition. Mass percent composition is the percentage of the mass of a component in a compound or mixture.

Let's assume that the total mass of the mixture is M. We can express the mass of each component in terms of M and the given mass percent composition.

The mass of component 3 (m3) is given as 300 g. We can express this in terms of M as: m3 = (W3/100) * M

Similarly, the mass of component 1 (m1) can be expressed as: m1 = (W1/100) * M

And the mass of component 2 (m2) can be expressed as: m2 = (W2/100) * M

Now, we can substitute the given values of W3, W1, and W2 into the equations to find m1 and m2.

Let's calculate m1 and m2:

m1 = (26/100) * M m2 = (8/100) * M

Since we don't have the value of M, we cannot calculate the exact values of m1 and m2. However, we can express them in terms of m3.

Substituting the values of m1 and m2 in terms of m3:

m1 = (26/100) * M = (26/100) * (m3 + m1 + m2) m2 = (8/100) * M = (8/100) * (m3 + m1 + m2)

Simplifying the equations:

m1 = (26/100) * (m3 + m1 + m2) m2 = (8/100) * (m3 + m1 + m2)

We can solve these equations to find the values of m1 and m2. However, since we have a circular dependency between m1 and m2, we cannot find their exact values without additional information.

In conclusion, without knowing the value of M or having additional information, we cannot determine the exact values of m1 and m2.
