Answer:
0.0014 moles is present in 40cm³ of 0.035M of HCl solution
Explanation:
Molarity = 0.035M
V = 40.0mL
1mL = 1cm³
V = 40cm³
0.035 moles = 1000cm³
X moles is present in 40cm³
X = (40 * 0.035) / 1000
X = 0.0014moles
0.0014 moles is present in 40cm³ of solution 
 
        
             
        
        
        
1.54 x 10⁶kW 
Explanation:
The problem here is converting from megawatts into kilowatts. 
   Given 1540megawatts. 
The mega- and kilo- watts are prefixes that denotes multiples of units. 
   1 megawatt = 10⁶watts
   1 kilowatt = 10³watts
Now given 1540megawatts power to Kilowatt power; 
    We see that : 
    1000kW = 1mW
  1540mW x  = 1.54 x 10⁶kW
 = 1.54 x 10⁶kW

Answer:  Molarity of  anions in the chemist's solution is 0.0104 M
 anions in the chemist's solution is 0.0104 M
Explanation:
Molarity : It is defined as the number of moles of solute present per liter of the solution.
Formula used :

where,
n= moles of solute
 
  
 = volume of solution in ml = 100 ml
 = volume of solution in ml = 100 ml
Now put all the given values in the formula of molarity, we get

Therefore, the molarity of solution will be 

As 1 mole of  gives 2 moles of
 gives 2 moles of 
Thus  moles of
  moles of  gives =
 gives =
Thus the molarity of  anions in the chemist's solution is 0.0104 M
 anions in the chemist's solution is 0.0104 M
