    Molarity = Number of moles of solute per litre of solution.
    Here, concentration is 10 mg/ml or 10 g L-1
    This means that 10 g RNA per litre Number of moles = given weight/molecular weight = 10 10000 = 10-3
    There are 10-3 moles per litre.

    Explanation:

    To determine the molarity of the RNA solution, we need to consider the molecular weight of RNA and the concentration of the solution.

    Molecular weight of RNA:
    It is given that each RNA has an average weight of 10 kDa (kilodaltons). To convert this into grams, we need to multiply it by the molecular weight conversion factor:
    1 kDa = 1 x 10^3 g/mol

    So, the molecular weight of RNA is:
    10 kDa = 10 x 10^3 g/mol = 10,000 g/mol

    Concentration of the RNA solution:
    The spectrophotometry measurement showed a concentration of 10 mg/ml.

    To convert this concentration into moles per liter (Molarity), we need to divide the concentration by the molecular weight of RNA.

    Calculating the molarity:

    Step 1: Convert the concentration from mg/ml to g/L:
    10 mg/ml = 10 x 10^-3 g/ml

    As there are 1000 ml in 1 L, the concentration in g/L will be:
    10 x 10^-3 g/ml x 1000 ml/L = 10 g/L

    Step 2: Calculate the number of moles of RNA in 1 liter of the solution:
    Number of moles = Concentration (in g/L) / Molecular weight (in g/mol)

    Number of moles = 10 g/L / 10,000 g/mol = 0.001 mol/L

    Step 3: Convert moles per liter to Molarity:
    Molarity (M) = Number of moles / Volume (in L)

    As we want the molarity in 1 L, the volume is 1 L:
    Molarity (M) = 0.001 mol/L / 1 L = 0.001 M

    Therefore, the molarity of the RNA solution is 0.001 M.
