A bottle of shampoo has a capacity of 0.43 L. How many milliliters of shampoo does the bottle contain? (1 L = 1,000 mL) A. 4.3 m
Finger [1]

Answer:

The correct answer is C

C. 430 mL

Step-by-step explanation:

We know that 1 liter is equivalent to 1,000 milliliters

1L = 1,000mL

So the number we have to go from liters to milliliters we multiply it by 1,000 and change the L per mL

0.43L = 0.43 * 1000 mL

0.43L = 430 mL

The bottle of shampoo contain 430 mL

if we look at the options they give us, we will see that it is equal to option c

A. 4.3 mL

B. 860 mL

C. 430 mL

D. 43 mL
