Answer:it a solution that can be easily saturated.
Explanation:
Answer: We need true value to find out who is more accurate.
Explanation:
Precision refers to the closeness of two or more measurements to each other.
Accuracy refers to the closeness of a measured value to a standard or known value.
For Example: If you weigh a given substance five times and you get 3.0 kg each time. Then the measurement is very precise.
For Example: If the mass of a substance is 3.0 kg and one person weighed 3.05 kg and another person weighed 3.2 kg. Then, the weight measured by first person is more accurate.
According to the question:
Density measured by Mary = 2.226 g
/ml
Density measured by Joseph= 2.335 g
/ml
As, the standard or known value is not given, we can not know which student’s value is more accurate
I think u need to be more specific on this question i would help sorry
<u>Answer:</u> The volume of barium chlorate is 195.65 mL
<u>Explanation:</u>
To calculate the volume of solution, we use the equation used to calculate the molarity of solution:
Given mass of barium chlorate = 25.0 g
Molar mass of barium chlorate = 304.23 g/mol
Molarity of solution = 0.420 mol/L
Volume of solution = ?
Putting values in above equation, we get:
Hence, the volume of barium chlorate is 195.65 mL
Answer: Formula: Mass = (Volume)(Density)
Iron Density = 7.87 g/cm^3
Volume of Iron = 55.2 cm^3
Mass=(V)(D)
Mass= (55.2 cm^3) x (7.87 g/cm^3)
Mass= 434,42 g
