No the Ratio of a mixture are not exact, one mixture might have more substance than the other but it is still a mixture.
yes. a ratio of two to one.
Mix ratio refers to the proportion of different components or ingredients that are combined to create a mixture. It specifies the ratio or proportion by weight, volume, or some other unit of measurement. For example, a mix ratio of 2:1 means that there are two parts of one component and one part of another component in the mixture.
The ratio for 200 ppm (parts per million) can be expressed as 200 parts of a substance per one million parts of the total solution or mixture. This means that in a solution containing 200 ppm of a substance, there are 200 units of that substance for every 1,000,000 units of the total solution. Thus, the ratio can be simplified as 200:1,000,000 or 1:5,000 when reduced.
The ratio of the constituents of a mixture cannot be determined.
If there are 5 parts of peanuts and 3 parts of cashews, there are 8 parts all together.If the total mixture is to weigh 24 ounces, each of the 8 parts will weigh 3 ounces.3 parts of cashews at 3 ounces each will be 9 ounces.5 parts of peanuts at 3 ounces each will be 15 ounces.9 ounces plus 15 ounces gives the correct total weight of 24 ounces
