2. What mass of sulphuric acid (density 1.84 g/
cm) can be held in a 250 ml bottle?

the range is 20

Step-by-step explanation:

so here is how you find the range here is an example

the range data is 42 , 28 , 41, and 22

you first order  the range data from least to greatest which is 22 , 28 , 41 , 42

after you order the numbers you want to get the largest number from the data and subtract it from the smallest number in the data which is 42 - 22 = 20

20 is the range
