Answer:
The closest answer would be 19g.
Step-by-step explanation:
1)The formula for density is mass divided by volume
2) That means you have to divide all the masses by 3.7 cm3 to find which one is closest to 5.2 g/cm3
The answer is 19.24g
Density of an object is defined as the ratio of the mass of the object to its volume. Mathematically;
Density = mass of the object /volume
Given;
Density = 5.2g/cm³
Volume = 3.7cm³
Mass = density × volume
Mass = 5.2×3.7
Mass = 19.24g
The mass of the object is 19.24g
Answer:D
If the interior angle is 168, then the exterior angle is 180 - 168, or 12. The 360 degrees is evenly distributed over all of the angles, so 360/12 = 30 sides. The formula for the sum of the angles in an n-sided polygon (in degrees) is 180(n-2).
