Question

If an object has a Mass of 11g and a volume fo 13mil, what is its density?

Answer 1

Answer:

$\boxed {\boxed {\sf B. \ d \approx 0.85 \ g/mL}}$

Explanation:

Density is found by dividing the mass by the volume.

$d=\frac{m}{v}$

The mass of the object is 11 grams and the volume is 13 milliliters.

$m= 11 \ g \\v= 13 \ mL$

Substitute the values into the formula.

$d= \frac{11 \ g}{13 \ mL}$

Divide.

$d=0.846153846 \ g/mL$

Round to the nearest hundredth. The 6 in the thousandth place tells us to round the 4 to a 5.

$d \approx 0.85 \ g/mL$

The density is about 0.85 grams per milliliter.
