Mathematics: The mass of a molecule of penicillin is 10^-18 kilogram and the mass of a molecule of insulin is 10^-23 kilogram. how many times greater is the mass of a molecule of penicillin than the mass of a molecule of insulin?

$\dfrac{\text{mass of penicillin}}{\text{mass of insulin}}=\dfrac{10^{-18}\,kg}{10^{-23}\,kg}=10^{-18-(-23)}=10^{5}$

The mass of a molecule of penicillin is 10⁵ times that of a molecule of insulin.

$10^{5}$ times

Step-by-step explanation:

Given : The mass of a molecule of penicillin is 10^-18 kilogram.

The mass of a molecule of insulin is 10^-23 kilogram.

Now, the number of times the mass of a molecule of penicillin is greater than the mass of a molecule of insulin :-

$\dfrac{10^{-18}}{10^{-23}}$

Using law of exponent :

$\dfrac{a^m}{a^n}=a^{m-n}$

we have,

$\dfrac{10^{-18}}{10^{-23}}=10^{-18-(-23)}=10^{-18+23}=10^{5}$

Hence, the mass of a molecule of penicillin is $10^{5}$ times greater than the mass of a molecule of insulin.
