Fluorine has the highest. Fluorine's electronegativity is 4.0
Answer:
Accuracy is the closeness to the specific target and precision is the closeness of the measurements to each other.
Answer:
0.0025moles
Explanation:
Molarity of a solution (M) = number of moles (n) ÷ volume (V)
According to this question, to make 250 mL of a 0.01 M solution of CaCl, the following number of moles is needed:
Volume = 250mL = 250/1000 = 0.250Litres.
Using; molarity = n/V
0.01 = n/0.250
n = 0.0025
n = 2.5 × 10^-3 moles.
A gas can move around freely while a solid is hard and can’t move around freely
