WebMay 10, 2024 · You can calculate the number of DNA molecules (per gram) in your DNA sample by: multiplying the amount of DNA in ng by Avogadro’s number (6.022 x 10e23). This value is then divided by the product of [the DNA length in base pairs x (1 x10e9) x 650]. Lab math – it’s a dreaded topic, isn’t it? WebJul 1, 2024 · Avogadro's Law shows that volume or pressure is directly proportional to the number of moles of gas. Putting these together leaves us with the following equation: P1 × V1 T1 × n1 = P2 × V2 T2 × n2 As with the other gas laws, we can also say that (P × V) (T × n) is equal to a constant.
