Darius buys a bottle of a chemical solution that contains 70, percent alcohol. The bottle contains 500 milliliters of solution.
Marianna [84]

Answer: There are 350 milliliters of alcohol in the bottle

Step-by-step explanation:

The amount of solution  contained in the bottle = 500 millilitres

The percentage of alcohol contained in  the bottle  of 500 millilitres= 70%.

Therefore  amount of alcohol in the solution is  70% of 500 millilitres

Step 2 --- Solving we have

70/100 × 500 =  0.70 x 500 =  350 ml

There are 350 millilitres of alcohol in the bottle.
