Aluminum has a density of 2.70 g/ml. calculate the mass (in grams) of a piece of aluminum having a volume of 381 ml . express your answer to three significant figures.

Mass ≈ 1030g (Three significant Figures)

Explanation:

We were given;

Density = 2.70 g/mL

Mass = ?

Volume = 381 mL

The relationship between all three parameters mentioned above is given by the formular below;

Density = Mass / Volume

Upon solving for Mass, we have;

Mass = Density * Volume

Substituting the respective values;

Mass = 2.7 * 381

Mass = 1028.7g

Mass ≈ 1030g (Three significant Figures)

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
