Density = mass/volume = 80 g/10cm³ = 8 g/cm³
Answer:
you can use the idea of molecular masses to calculate easily
Answer:
85% of 20 is 17
Explanation:
You can multiply 85% and 20 or subtract 85% from 20.
Answer:
a. liquid
b. solid
c. gas, (should be at it's boiling point)
Explanation: If the normal melting point of a substance is below room temperature, the substance is a liquid at room temperature. Benzene melts at 6°C and boils at 80°C; it is a liquid at room temperature. If both the normal melting point and the normal boiling point are above room temperature, the substance is a solid.

Answer:
Rate of formation of SO₃ = 7.28 x 10⁻³ M/s
Explanation:
According to equation 2 SO₂(g) + O₂(g) → 2 SO₃(g)
Rate of disappearance of reactants = rate of appearance of products
⇒ -----------------------------(1)
Given that the rate of disappearance of oxygen = = 3.64 x 10⁻³ M/s
So the rate of formation of SO₃ = ?
from equation (1) we can write
⇒ = 2 x 3.64 x 10⁻³ M/s
⇒ = 7.28 x 10⁻³ M/s
∴ So the rate of formation of SO₃ = 7.28 x 10⁻³ M/s
