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

0.82

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.

Answer 2

The specific gravity of kerosene is 0.82

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=(x)/(y)`

we have

`x=0.82\ g\\y=1\ g`

substitute the values

`z=(0.82)/(1)=0.82`
