Answer:
A)16.3% (Hexane's formula is C6H14)
If the cube is 3 cm on each side, then it has a volume of 27 cm^3 (3 x 3 x 3). Density is mass divided by volume, so its density is 72.9/27 = 2.7 g/cm^3.
<span>Going by the density, the cube is made of Aluminium - density is a fairly unique quantity</span>
Sure. Whith what do you need help?
A) divide by 100. A meter is 100 centimeters so that’s how you can tell
Answer:
1.64 L
Explanation:
P₁V₁ = P₂V₂
P₁ = 2.25 atm
V₁ = 0.75 L
P₂ = 1.03 atm
V₂ = ?
(2.25 atm)(0.75 L) = (1.03 atm)V₂
[(2.25 atm)(0.75 L)]/(1.03 atm) = V₂
V₂ = 1.64 L
