Answer: thats just the answer
Step-by-step explanation:
The expression "24g/l" represents a concentration measurement. The "g" stands for grams, which is a unit of mass, and the "l" stands for liters, which is a unit of volume. When these units are combined, it means that there are 24 grams of a substance in every liter of solution.
To express this measurement using two significant figures, we need to round the number. The general rule for rounding is that if the digit to be dropped is 5 or greater, we round up, and if it is less than 5, we round down.
In this case, since the number we are rounding is 4, which is less than 5, we round down. Therefore, the concentration of the solution would be 24g/l.
Here's an example to illustrate this:
Let's say we have a solution of saltwater, and we want to find the concentration of salt in the solution. If we measure 24.56 grams of salt and dissolve it in 1 liter of water, the concentration would be 24.56g/l. However, when we round this to two significant figures, it becomes 24g/l.
So, the answer to the question "24g/l Express your answer using two significant figures" is simply 24g/l.
