Answer: Measures the amount of space occupied by an object
Equals the displacement of an object in water Lacks physical dimension Can be measured in milliliters or cubic centimeters
Explanation:
Answer:
Mass of benzene required = 0.78 g
Explanation:
Given data:
Mass of CO₂ produced = 2.66 g
Mass of benzene required = ?
Solution:
Chemical equation:
2C₆H₆ + 15O₂ → 6H₂O + 12CO₂
Number of moles of CO₂:
Number of moles = mass/molar mass
Number of moles = 2.66 g/ 44 g/mol
Number of moles = 0.06 mol
Now we will compare the moles of CO₂ with C₆H₆.
CO₂ : C₆H₆
12 : 2
0.06 : 2/12×0.06=0.01 mol
Mass of benzene required:
Mass = number of moles × molar mass
Mass = 0.01 mol × 78.11 g/mol
Mass = 0.78 g
Organisms decay in a solution. Minerals dissolve and crystalize. Rock fragments squeeze together
Hello!
To find the density of any object, we will need to use the formula: d = m/V.
In this formula, d is the density, m is the mass and V is the volume.
We are given the volume and mass. The volume is 12 cubic centimeters and the mass is 32 grams. With these values, we can find the density using the formula.
d = 32 grams / 12 cm³
d = 8/3 grams/cm³
d ≈ 2.67 g/cm³
Therefore, it's density is equal to about 2.67 g/cm³.
