It is impossible to narrow down anything about the unknown.
Flame tests are common analytical techniques used to determine the composition of an unknown compound based on the color that it imparts to flame. Each metal ion imparts a specific color to flame which helps us to identify it.
In this case, two colors were visible in the flame and it will be difficult to determine which of the colors corresponds to the actual metal ion present.
Therefore, it is impossible to narrow down anything about the unknown.
the molar mass is how many grams it takes to make a full mole. The number in carbon 12 tells us that it takes 12 g to makes a mole, so one half of that would be <u><em>option d, 0.5</em></u>.
