Kristen has 7.5ml of water and her lab partner Rebecca has 2.3l. how many total microliters do they have?

1 liter=1,000 mililiters

1 liter=1,000,000 microliters

1milliliter=1,000 microliters

milli=thousand

micro=million

Convert 2.3liters⇒2,3000ml by multiplying by 1,000

2,300ml+7.5ml=2,307.5ml

Multiply 2,307.5ml by 1,000 microliters

2,307.5ml*1,000=2,307,500 microliters

There are 2,307,500 microliters

There are 2,307.5 millilitres (divide by 1,000)

There are 2.3075liters (divide by 1,000)
