Total call including 6500 'yes' and 4100 'no' are 10600 and on each call there was a fifty cent charge. Total charge becomes 5300 $ so this is very straight forward data. And from this test two types of classes are made with cleared population in each class and such cleared population division is example of stratified sampling so this is right answer.
Answer:- 0.0634 M
Explanation:
molarity is defined as the number of moles of solute in 1 L of solution
molar mass of Ni(NO₃)₂ - 182.7 g/mol
number of moles of Ni(NO₃)₂ - 5.80 g/ 182.7 g/mol = 0.0317 mol
number of moles in 500 mL - 0.0317 mol
therefore number of moles in 1000 mL - 0.0317 mol / 500 mL x 1000 mL/L
molarity of the solution is - 0.0634 M
