70 ml

Further explanation

Given:

2.1 liters of coffee were equally distributed to 30 cups.

Question:

How many milliliters of coffee were in each cup?

The Process:

Step-1: converting liters into milliliters

Recall $\boxed{ \ 1 \ liter = 1,000 \ milliliters \ }$

Let us change the 2.1 liters unit of coffee into milliliters.

$\boxed{ \ 2.1 \ liters \times \frac{1,000 \ mL}{1 \ liter} = \ ? \ }$

$\boxed{ \ = 2.1 \times 1,000 \ mL} \ }$

$\boxed{ \ = 21 \times \frac{1}{10} \times 1,000 \ mL} \ }$

$\boxed{ \ = 21 \times 100 \ mL} \ }$

$\boxed{\boxed{ \ 2,100 \ mL \ }}$

Therefore, 2,100 mL of coffee are available for distribution.

Step-2: calculating how many milliliters of coffee were in each cup

$\boxed{ \ 30 \ cups = 2,100 \ mL \ }$

$\boxed{ \ 1 \ cups = \ ? \ mL \ }$

We have to divide the total amount of coffee by the number of cups.

$\boxed{ \ 1 \ cup \times \frac{2,100 \ mL}{30 \ cups} \times 1,000 \ mL = \ ? \ }}$

$\boxed{ \ = \frac{2,100}{30} \ }$

The numerator and denominator are equally divided by 10.

$\boxed{ \ = \frac{210}{3} \ }$

$\boxed{ \ = 210 \div 3 \ }$

$\boxed{\boxed{ \ 70 \ }}$

Thus, 70 milliliters of coffee were in each cup.
