Calculate the mass of 2.00 X 1020 molecules of SO3.

Chemistry
1 answer:
MakcuM [25]3 years ago
8 0

Answer:

0.027g

Explanation:

From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 molecules.

From the above, it means that 1mole of SO3 also contains 6.02x10^23 molecules.

1mole of SO3 = 32 + (16x3) = 32 + 48 = 80g

If 1 mole (80g) of SO3 contains 6.02x10^23 molecules,

Then Xg of SO3 will contain 2x10^20 molecules i.e

Xg of SO3 = (80x2x10^20)/6.02x10^23 = 0.027g

nataly862011 [7]

Answer:

transferred

Energy

Explanation:

Energy is the ability to change the state of bringing about a work leading to movement or generating electromagnetic radiation. There are actually many forms of energy. So, kinetic energy is a form of energy related to the movement of a body. The combustion, in turn, retrieves the potential energy chemical contained in fuels. Solar panels capture light energy to transform it into electrical energy.

Sphinxa [80]

Answer:

P_4_{(I)}+5O_2_{(g)}+6H_2O_{(l)}\rightarrow +4H_3PO_4_{(l)}

Explanation:

The first step is:

P_4_{(I)}+5O_2_{(g)}\rightarrow 2P_2O_5_{(g)}

Second step is:

P_2O_5_{(g)}+3H_2O_{(l)}\rightarrow 2H_3PO_4_{(l)}

Multiplying second step by 2, and adding both the steps, we get that:

P_4_{(I)}+5O_2_{(g)}+2P_2O_5_{(g)}+6H_2O_{(l)}\rightarrow 2P_2O_5_{(g)}+4H_3PO_4_{(l)}

Cancelling common species, we get that:

P_4_{(l)}+5O_2_{(g)}+6H_2O_{(l)}\rightarrow +4H_3PO_4_{(l)}
