Question

using the table of equalities, calculate the number of gallons (gal) in 855 milliliters (ml). 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; 1 dl = 100 ml; 1 ml = 1 cm³	1 qt = 4 cups; 1 qt = 2 pt; 1 gal = 4 qt	946 ml = 1 qt; 1 l = 1.06 qt
mass	1 kg = 1000 g; 1 g = 1000 mg	1 lb = 16 oz	1 kg = 2.20 lb; 454 g = 1 lb
time	1 h = 60 min; 1 min = 60 s	1 h = 60 min; 1 min = 60 s

0.904 gal
1.11 gal
0.277 gal
0.226 gal

Explanation:

Step1: Convert milliliters to liters

We know that $1\ L = 1000\ mL$. So, for $855\ mL$, the volume in liters is $V_{L}=\frac{855}{1000}= 0.855\ L$.

Step2: Convert liters to quarts

From the table, $1\ L=1.06\ qt$. So the volume in quarts is $V_{qt}=0.855\times1.06 = 0.9063\ qt$.

Step3: Convert quarts to gallons

Since $1\ gal = 4\ qt$, the volume in gallons is $V_{gal}=\frac{0.9063}{4}=0.226575\ gal$.
Rounding to three - significant figures, we get $0.226\ gal$.

Answer:

0.226 gal
