Answer:
a. 599 cm³
b. 1.49 g/cm³
Explanation:
<h3>A. Volume </h3>
Volume is the amount of space an object occupies. Since this is a brick, the object is a rectangular prism. The formula for the volume of a rectangular prism is the product of length, width, and height.
The brick's length (l) is 13.77 centimeters, the width (w) is 8.50 centimeters, and the height (h) is 5.12 centimeters. Substitute these values into the formula.
Multiply the numbers together.
The original measurements have at least 3 significant figures, so our answer must have 3. For the number we calculated, that is the ones place. The 2 in the tenths place tells us to leave the 9 in the ones place.
<h3>2. Density </h3>
Density is the amount of matter in a specified space. The formula for density is mass over volume.
The mass of the brick is 895.3 grams and we just found the volume to be 599.2704 cubic centimeters. Substitute the values into the formula.
Divide.
Round to three significant figures. For the number we calculated, that is the hundredth place. The 4 in the thousandth place tells us to leave the 9 in the hundredth place.
Answer:
As temperature increases, a substance will change from solid, to liquid, to gas. ... Apply Butter is made by intentionally changing the density of liquid milk.
Explanation:
Answer:
The percentage of germanium in germatite is 6.0003%.
Explanation:
Mass of an ore of germanite = 1.00 grams
Mass of germanium chloride = 0.177 grams
Percentage of germanium in germanium chloride = 33.9%
Let the mass of germanium present in germanium chloride be x.
Percentage of an element in a compound:
x = 0.060003 grams
Percentage of germanium in an ore of germanite:
The percentage of germanium in germatite is 6.0003%.
