An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients
Reaction
Cu + 4HNO₃ → Cu(NO₃)₂ + 2NO₂ + 2H₂O
mol of Cu(MW=63.55 g/mol) :
mol ratio Cu : Cu(NO₃)₂ = 1 : 1, so mol Cu(NO₃)₂ :
mass of Cu(NO₃)₂ (MW=187,56 g/mol) :
10.28 g of Cu(NO₃)₂ are obtained from the reaction⇒actual yield
Given: Mixture of vitamin water = 75% pure water & 25% concentrated vitamin drink. To find: Quantity of water to be added to 16 gallons of concentrated vitamin drink to prepare a tank of vitamin water. Solution: Let total amount of mixture be x. 25% of x = 16 gallons (from given information) When 25% of x is 16 gallons, the remaining 75% of x will be calculated as below: (16/25)*75 = 48 Answer: 75% of x = 48 gallons. This means 48 gallons pure water is required to be added to mixture to prepare a tank of vitamin water.
1. She would want a balanced force so she doesn't fall but, well, keep her balance. 2. Frictional force because when an object slows down it's because a higher amount of friction is acting on it. 3. It would be magnitude and direction because is like the size of the object and they need to know how much force it will take to move it. 4. Is the same as 3... 5. A push and a pull are a force.
