a chemistry student requires 250 miligramsof a chemicalfor a particular experiment. she has 30grams of the chemical. how many times can the student carry out the experiment?
30/.25 = 120
Can i have a working for it please
Working please
To determine how many times the student can carry out the experiment, we need to calculate how many 250 milligram (mg) portions can be obtained from the available 30 grams (g) of the chemical.
First, we need to convert grams to milligrams since the required amount is given in milligrams.
1 gram (g) = 1000 milligrams (mg)
So, we have:
30 grams * 1000 = 30,000 milligrams
Now, we can calculate the number of experiment portions:
Number of portions = Total amount / Amount per portion
Number of portions = 30,000 mg / 250 mg
Dividing 30,000 mg by 250 mg:
30,000 mg / 250 mg = 120
Therefore, the student can carry out the experiment 120 times with the given amount of 30 grams of the chemical.
