Answer:

<h2>3 ounces</h2>

Step-by-step explanation:

Step one:

given data

the initial amount of chemical = 1.25 ounces

Extra amount of chemical =2.5 ounces

Total amount of chemical =1.25+2.5=3.75 ounces

Step two:

we are told that the scientist used 0.75 ounces of chemical

Hence the remaining chemical is

remaining= 3.75-0.75

remaining= 3 ounces

<u>The remainder is 3 ounces</u>
