Question

using the table of equalities, calculate the number of quarts (qt) in 4.0 liters (l). remember to select an answer with the correct number of significant figures.
some common equalities

quantity	metric (si)	u.s.	metric - u.s.
volume	1 l = 1000 ml<br>1 dl = 100 ml<br>1 ml = 1 cm³	1 qt = 4 cups<br>1 qt = 2 pt<br>1 gal = 4 qt	946 ml = 1 qt<br>1 l = 1.06 qt
mass	1 kg = 1000 g<br>1 g = 1000 mg	1 lb = 16 oz	1 kg = 2.20 lb<br>454 g = 1 lb
time	1 h = 60 min<br>1 min = 60 s	1 h = 60 min<br>1 min = 60 s

8 quarts
4.2 quarts
3.8 quarts
1.06 quarts
i dont know yet

Explanation:

Step1: Identify conversion factor

From the table, 1 L = 1.06 qt.

Step2: Calculate number of quarts

Multiply the given volume in liters by the conversion factor. For 4.0 L, we have $4.0\times1.06 = 4.24$ qt.

Step3: Consider significant figures

The number 4.0 has 2 significant figures. So, rounding 4.24 to 2 significant figures gives 4.2 qt.

Answer:

4.2 quarts
