Answer:
Explanation:
Hey,
so here the student is saying that the given mass is of one atom. But when we usually talk about amu it is the unified atomic mass so mass of all the atoms present.
So that's why he is wrong.
Also the definitions states,
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
Answer:
An agricultural drone is an unmanned aerial vehicle used to help optimize agriculture operations, increase crop production, and monitor crop growth. Sensors and digital imaging capabilities can give farmers a richer picture of their fields.
Explanation:
Drones can help farmers to optimize the use of inputs (seed, fertilizers, water), to react more quickly to threats (weeds, pests, fungi), to save time crop scouting (validate treatment/actions taken), to improve variable-rate prescriptions in real time and estimate yield from a field.
A chemical formula can be used to determine the makeup of a substance. It tells you what elements make up a particular substance, like H2O is the chemical formula of water.
Answer:
Mass = 365.45 g
Explanation:
Given data:
Number of moles of HNO₃ = 5.8 mol
Mass of HNO₃ = ?
Solution:
Formula:
Mass = number of moles × molar mass
Molar mass of HNO₃ = 63.01 g/mol
by putting values,
Mass = 5.8 mol × 63.01 g/mol
Mass = 365.45 g
