The capacity for doing work is Energy.
Answer:
1.0798 × 10^2kg
Explanation:
1 mg = 1 × 10-6 kg therefore we can multiply 10798 by 1 × 10-6 we will get the amount of kg.
10798 × (1 × 10-6) = 1.0798 × 10^2kg
Answer: 0.25M
Explanation:
Molarity : It is defined as the number of moles of solute present in one liter of solution.
Given mass of = 73.5 g
Molar mass of = 98g/mol
Volume of solution = 3.0L
The Mass number is 65, Copper-65
To find the mass number you add the number of protons to the number of neutrons.
Benzoic acid is able to dissolve in hot solvents. That means that it would not be filtered out by the buchner funnel since the buchner funnel has holes in it that make it so that the solvent can get through but solids can't (the benzoic acid would be dissolved in the solvent and therefore would leave the funnel with the solvent through the holes).
Note that it is important that the solvent is hot. Benzoic acid will start to precipitate out (re crystallize) as soon as the temperature drops which will make it so that some of the benzoic acid would get caught in the buchner funnel.
I hope this helps. Let me know in the comments if anything was unclear.
