What is the concentration (g/L) of an albumin solution made by mixing 0.20 mL of 6.0 g/L solution with 2.72 mL BCG reagent? Assume volumes are additive.

0.41g/L

Explanation:

To find the concentration of the albumin in the mixture we need to find the mass in grams and the volume in liters of the solution:

Mass of albumin:

0.20x10⁻³L * (6.0g / L) = 1.2x10⁻³g of albumin

Volume of the solution:

0.20mL + 2.72mL = 2.92mL = 2.92x10⁻³L

Thus, concentration of albumin is:

1.2x10⁻³g of albumin / 2.92x10⁻³L =

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
