Molar mass of N_2O=44g/mol
Mass of N_2O formed
44(3.4)=132.16gThe mass of nitrous oxide that can be formed from 48.7 g of nitrogen is approximately 76.525 grams. To calculate the mass of nitrous oxide (N₂O) formed from a given mass of nitrogen (N₂), one needs to consider the balanced chemical equation.
N₂+ O₂ -> N₂O
The balanced equation tells us that 1 mole of nitrogen (N₂) reacts with 1 mole of oxygen (O₂) to produce 1 mole of nitrous oxide (N₂O).
Given mass of nitrogen (N₂) = 48.7 g
To find the number of moles of nitrogen (N₂), one divide the given mass by the molar mass of nitrogen, which is approximately 28.02 g/mol.
Number of moles of N₂= 48.7 g / 28.02 g/mol ≈ 1.738 mol
The balanced equation shows that 1 mole of nitrogen (N₂) reacts to form 1 mole of nitrous oxide (N₂O).
So, the number of moles of nitrous oxide (N₂O) formed is also approximately 1.738 mol.
To find the mass of nitrous oxide (N₂O), one multiply the number of moles by its molar mass, which is approximately 44.01 g/mol.
Mass of N₂O = 1.738 mol × 44.01 g/mol ≈ 76.525 g
Therefore, the mass of nitrous oxide formed from 48.7 g of nitrogen is approximately 76.525 grams.

○ Coefficients in chemical formulas
The law of multiple proportion account for subscripts in chemical formulas (option A).
What is law of multiple proportion?The law of multiple proportion states that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
For example, nitrogen dioxide and nitrogen tetroxide have nitrogen to oxygen ratios of 1:2 and 1:4.

A student began with a 3.12 g sample that contained their unknown and charcoal. After recrystallization the mass of dried crystals recovered was 2.61 g. What was the percent recovery
The percent recovery would be 83.65%
What is Percent Recovery?The percent recovery of a recrystallization reaction can be mathematically deduced as:
Percent recovery = recovered amount/amount of original sample x 100%
In this case, the recovered amount = 2.61 g, and the original amount of sample = 3.12. Thus:
Percent recovery = 2.61/3.12 x 100%
= 83.65%

2. Using Boyle’s Law, calculate the new volume of the weather balloon at a higher altitude. Assume the volume of the balloon at ground level is 10.0 m3 where the atmospheric pressure is 1.00 atm. What will be its new volume at an altitude of 15 km where the atmospheric pressure is 0.350 atm? Fill in the equation with the correct values and solve for the new volume of the weather balloon.
Answer:

Using the Boyle's law, the volume of the gas at 15 Km is [tex]28.6 m^3[/tex].
What is Boyle's law?Boyle's law states that, the volume of given mass of gas is inversely proportional to its pressure at constant temperature. Since pressure decreases with height, the volume will increase at higher altitude.
