You did not post up the options, however we can balance this equation ourselves simply by adding multipliers to the front of each reactant and product until all atoms balance. Start with one atom type, say hydrogen, then move to the next and next and keep repeating this process.

2NH3 + O2 ⇒ 2NO + 3H2O

This balances nitrogens and hydrogens, but we still can't balance oxygen, so have to multiply up further

4NH3 + 5O2 ⇒ 4NO + 6H2O

This now balances all 3 atom types for reactants and products.

What is the concentration of a suspension that grew 89 colonies on a plate with a dilution of 1:100?
mafiozo [28]

Answer:

8900 CFU/mL

Explanation:

Colony Forming Units (CFU) is a value that indicates the degree of microbiological contamination of an environment. It expresses the relative number of microorganisms of a given taxon in a volume of one cubic meter of water.

UFC is the minimum number of separable cells on the surface, or inside, of a semi-solid agar medium that results in the development of a visible colony of the order of tens of millions of descending cells. The CFUs can be pairs, chains or clusters, as well as individual cells. Colony forming unit.

Calculation

Colonies * Dilution = CFU/mL

89          *  (100/ 1 mL) = CFU/mL

8900 CFU/mL
