What is the molarity of a 5.00x10^2 mL solution containing 21.1 g of potassium bromide (KBr)? The molar mass of KBr is 119.0 g/m
Dominik [7]
Volume of solution in liters:

5.00 x 10² mL / 1000 => 0.5 L 

number of moles:

mass of solute / molar mass

21.1 / 119.0 => 0.1773 moles

Molarity = number of moles / volume 

M = 0.1773 / 0.5

M = 0.355 mol/L

Answer C

1. 10.0 g of CaCO 3 ​ on heating gave 4.4 g of CO 2 ​ and 5.6 g of CaO. The observation is in agreement with the law of conserva
finlep [7]

Answer:

  1. According to the law <br> Mass of reactants = mass of product, here <br> `underset(10 g)(CaCO_(3))rarr underset(4.4 g)(CO_(2))+underset(x)(CaO)` <br> Hence, x = 10 g - 4.4 g = 5.6 g <br> Which is mass of CaO.d
  2. In the first compound <br> Hydrogen = 5.93 % <br> Oxygen = `(100-5.93)% = 94.07 %` <br> In the second compound <br> Hydrogen = 11.2 % <br> Oxygen `= (100-11.2)%=88.8%` <br> In the first compound the number of parts by mass of oxygen that combine with one part by mass of hydrogen `=(94.07)/(5.93)=15.86` parts ...
