Answer:
78.75g
Explanation:
The density of diamond is the mass of diamond per unit of its volume. The density of a substance is calculated using the formula:
Density (g/cm^3) = mass (g) / volume (cm^3)
According to the question, the density of diamond= 3.15g/cm^3, volume of diamond= 25cm^3, mass = ?
Hence, to calculate the mass, we say;
Mass = Volume × density
Mass = 25 × 3.15
Mass = 78.75
Therefore, the mass of diamond is 78.75grams.
1) No. of atoms of all elements participating in the reaction are to be balanced.
2) Pressure Change should be noted (because, if ∆P≈0, it shows the reaction is in equilibrium).
3) The theoretical representation of the reaction should be balanced well.
Answer:
It would be True
Explanation:
Because they both have the same push of gravity. Gravity affects all objects equally. If you drop an egg and a watermelon at the same time they would both collide with the floor at the same time.
