The average density of a planet is 3.05 g/cm3. What is its density in kg/m3? (Enter your answer in scientific notation.)

For KNO₃, the mass is 346g. The molar mass can be computed as (39.098) + (14) + (15.99*3), which results in 101.068 gmol⁻¹. The volume of the solution is given as 750ml, equivalent to 0.75dm³. The formula for molarity is (mass of solute/molar mass of solute)*(1/volume of solution in dm³). Accordingly, molarity = (346/101.068)*(1/0.75), yielding 4.56 mol dm⁻³.

The density is 1.03 g/cm³. Explanation: The density of a substance is calculated with the formula: 1 kg = 1000 g therefore 2.06 kg = 2060 g. 1 L = 1000 cm³ thus 2 L = 2000 cm³. We now find: Mass = 2060 g Volume = 2000 cm³. Thus, the final answer of density is: 1.03 g/cm³. I hope this information assists you.

Answer:

No

Explanation:

When heated, tin could react with alkali metals, releasing hydrogen gas.

The calculated theoretical yield of ammonia is 29.58 Kg

In the solution provided,

the mass of is 5.22 Kg, which equals 5220 g

the mass of is 31.5 Kg, equivalent to 31500 g

The molar mass of is 2 g/mole

The molar mass of is 28 g/mole

The molar mass of is 17 g/mole

First, we must calculate the moles of and .

Moles of =

Moles of =

Next, we need to find which reagent is limiting and which is excess.

The balanced equation for the reaction will be,

Based on the balanced equation, we find that

1 mole of reacts with 3 moles of

1125 moles of react with moles of

This indicates that is the limiting reagent and is in excess.

Now, we proceed to calculate the moles of ammonia.

According to the reaction, we determine that,

3 moles of will yield 2 moles of ammonia

2610 moles of will provide moles of ammonia

Finally, we will calculate the mass of the ammonia produced.

Therefore, the theoretical yield of ammonia is 29.58 Kg
