Question

1. convert 240 ml of milk into cups.

volume in cups = $\frac{240 \text{ml}}{236.588 \text{ml/cup}}$
$=1.0$

1. convert 68.75 grams of cocoa powder into teaspoons.

$= 13.75 \text{tsp}$

1. convert 13.75 grams of sugar into tablespoons.

$= 2$

1. convert $1.3 \times 10^{-3}$ cups of salt into pinches.

$(1.3 \times 10^{-3}) \times (240 \text{pinches/cup})$
$=0.31$

1. convert $1.1 \times 10^{-3}$ liters of vanilla extract into drops.

$=8$
iometry unit

Explanation:

Step1: Use standard cup-mL conversion

1 US cup = 236.588 mL.
$\text{Volume in cups} = \frac{240\ \text{mL}}{236.588\ \text{mL/cup}}$

Step2: Calculate the value

$\text{Volume in cups} \approx 1.014 \approx 1.0$

Step1: Use cocoa powder tsp conversion

1 tsp cocoa powder ≈ 5 grams.
$\text{Volume in teaspoons} = \frac{68.75\ \text{g}}{5\ \text{g/tsp}}$

Step2: Calculate the value

$\text{Volume in teaspoons} = 13.75$

---

Step1: Use sugar tbsp conversion

1 tbsp sugar ≈ 12.5 grams.
$\text{Volume in tablespoons} = \frac{13.75\ \text{g}}{12.5\ \text{g/tbsp}}$

Step2: Calculate the value

$\text{Volume in tablespoons} = 1.1$

Step1: Use cup-pinch conversion

1 cup salt = 480 pinches.
$\text{Amount in pinches} = 1.3 \times 10^{-3}\ \text{cups} \times 480\ \text{pinches/cup}$

Step2: Calculate the value

$\text{Amount in pinches} = 0.624$

Step1: Convert liters to mL, use drop conversion

1 liter = 1000 mL, 1 mL vanilla extract ≈ 20 drops.
First convert liters to mL: $1.1 \times 10^{-3}\ \text{L} = 1.1\ \text{mL}$
$\text{Amount in drops} = 1.1\ \text{mL} \times 20\ \text{drops/mL}$

Step2: Calculate the value

$\text{Amount in drops} = 22$

Answer:

1. $\approx 1.0$ cups
2. $13.75$ teaspoons
3. $1.1$ tablespoons
4. $0.624$ pinches
5. $22$ drops
