- Oxygen (O) has a molar mass of approximately 16 g/mol. Therefore, the total mass from oxygen is: 16g/mol- Adding these together gives the molar mass of H₂O: Molar mass of H₂O=2g/mol+16g/mol=18g/mol Step 2: Calculate the number of moles of H₂O in 1.8 gTo find ...

(D). 18 ml of water. Hence, from all the values, we can see that the number of molecules of water is maximum $6.022 \times {10^{23}}$ in 18ml of water. So,
The researchers increased the number of metal-binding sites per antibody to decrease the amount of immunoconjugate, in mg, required to deliver a therapeutic dose of radiometal. Furthermore, the low amount of injected tracer (picomoles to nanomoles, sum of radioactive, and stable molecules) enab...
