Answer:
His drives are neither precise not accurate
Explanation:
It is true that his drives are neither precise nor accurate.
Accuracy is the exactness of measurement. It is the closeness of measured values to the true values.
In this problem, the true value is 250 yards, the measured values are 190 yards, 195 yards and 187 yards.
We can conclude that these numbers are very far from the true values. By virtue of that, they are inaccurate.
Precision is the ability to reproduce a set of experimental values. It is the closeness of the measured values to one another.
Jared failed to replicate his measured values over the three trials and so, his readings are not precise.
Therefore, his measurements are both imprecise and inaccurate.
Plastic bags are required to contain warnings after showing from several studies that they are a suffocation risk. For plastic bags with a thickness of less than one mil (1/1000 inch) having an opening
size of five inches or more, the following warning statement will meet the requirements of all
state and local laws: “Warning: To avoid danger of suffocation, keep this plastic bag away
from babies and children. Do not use this bag in cribs, beds, carriages, or playpens. This
bag is not a toy.”
Answer : The volume of solution will be, 0.309 L
Explanation : Given,
Mass of = 449.4 g
Molar mass of = 132 g/mole
Concentration = 11 M
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the volume of solution will be, 0.309 L
