What is normality and molarity of the concentration of solution?
2 answers:
Answer:
<u>Molarity and normality describe the numbers (moles) of reactants or products dissolved in one liter of solution.</u> Molarity: M = moles of solute contained in one liter of solution. ... <u>Normality is always a multiple of molarity. It describes the “equivalent” moles of reactants involved in chemical reactions.</u>
Explanation:
Normality is a measure of concentration equal to the gram equivalent weight per litre of solution. Gram equivalent weight is the measure of the reactive capacity of a molecule. The solute's role in the reaction determines the solution's normality. Normality is also known as the equivalent concentration of a solution.
Molar concentration is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution.
Formula for Molar: M =

Answer:
radiation
Explanation:
Based on the scenario being described in the question it can be said that the type of heat transfer that is being modeled is radiation. Like demonstrated in the picture attached below, radiation involved the transfer of heat through rays, waves, or particles as opposed to fluids or gases. Which is what is happening in this scenario, since the individuals are building up heat by moving and that heat is being passed on to the individuals around them through waves.
Answer:
Sara's percentage yield of gas mileage is approximately 90.7%
Explanation:
Percentage yield of an process is given by the ratio of the observed, experienced (calculated), or actual yield to the theoretical yield of the process and then multiplying the result by 100%
The theoretical yield of Sara's car is the mileage advertised for the car which the car has 'ideally' which is 43 miles per gallon
∴ The theoretical yield = 43 miles/gallon
The actual yield is the yield of the car Sara is able to calculate, based on how she uses the car which is 39 miles per gallon
∴ The actual yield = 39 miles/gallon
Sara's percentage yield of gas mileage for the car, % yield, therefore is given as follows;
% yield = (39 miles/gallon)/(43 miles/gallon) × 100 ≈ 90.7%
Sara's percentage yield of gas mileage, % yield ≈ 90.7%.
