Answer:
The order of decreasing mass is: I - Fe-Mn- N
Explanation:
According to the periodic table the atomic masses of the elements of the statement are:
IODE (I): 126, 90447
IRON (Fe): 55,845
MANGANESE (Mn): 54, 938844
NITROGEN (N): 14, 0067
Answer:
67.7 °C
Explanation:
Since this solution has 2 substances, but not in the same proportion, you need to consider the fraction molar of each one and the boling point, it will be expected a higher temperature than the lower boiling point and a lower boiling point of the highest boiling point.
46 °C x 0.69 = 31.74 °C
116°C x 0.31 = 35.96 °C
You add both: 31.74 °C + 35.96°C = 67.7 °C
To calculate the molar mass of substance, divide the number of moles by the given mass of substance.
The quantity of a substance is known as a mole. You can measure it in terms of grams, liters, atoms, molecules, or particles.
Use the substance's molar mass to convert between grams and moles. Divide the given mass by the number of moles to convert from moles to molar mass.
Using the formula, Number of moles = Given mass/ molar mass
The molar mass of a substance can be calculated as-
Molar mass = Given mass/number of moles
