The molarity of KBr solution is 1.556 M
molarity is defined as the number of moles of solute in volume of 1 L solution.
the number of KBr moles in 1 L - 1.556 mol
Therefore in 200.0 L - 1.556 mol/L x 200.0 L = 311.2 mol
Molar mass of KBr - 119 g/mol
mass of Kbr - 311.2 mol x 119 g/mol = 37 033 g
mass of solute therefore is 37.033 kg
The ionic form of the unbalanced equation
MnO2 +HNO2 = Mn(NO3)2 +H2O is as below
MnO2(s) + H^+(aq) + NO2^-(aq) = Mn^2+(aq) + No3^-(aq) + H20(l)
MnO2 does not dissociate since it is in solid state. In addition H2O is in liquid state thus does not dissociate in to ions
Answer: Atomic Particles
Explanation:
toms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
Answer:
2.268
Explanation:
5 lb × 0.45359237
= 2.26796185 kg
How to convert Pounds to Kilograms
1 pound (lb) is equal to 0.45359237 kilograms (kg).
1 lb = 0.45359237 kg
The mass m in kilograms (kg) is equal to the mass m in pounds (lb) times 0.45359237:
m(kg) = m(lb) × 0.45359237
Example
Convert 5 lb to kilograms:
m(kg) = 5 lb × 0.45359237 = 2.268 kg
Hope this helped!!!
