Question

The specific gravity of a substance is the ratio of its weight to the weight of an equal volume of water. Kerosene weighs 0.82 gram per cubic centimeter and water weighs 1 gram per cubic centimeter. What is the specific gravity of kerosene?

Answer 1

Answer:

The specific gravity of kerosene is 0.82

Step-by-step explanation:

Let

x -----> the weight in grams of a cubic centimeter of Kerosene

y ----> the weight in grams of a cubic centimeter of water

z ---> the specific gravity of a substance

so

$z=\frac{x}{y}$

we have

$x=0.82\ g\\y=1\ g$

substitute the values

$z=\frac{0.82}{1}=0.82$

Answer 2

Answer:

0.82

Step-by-step explanation:

The specific gravity of a substance is the ratio of its weight to the weight of an equal volume of water. Kerosene weighs 0.82 gram per cubic centimeter and water weighs 1 gram per cubic centimeter. Therefore, the specific gravity of kerosene is 0.82.
