Question

Volume of one molecule of water is:

(Density of water = $1$ g/cc)

• A. $6.02\times {10}^{-23}$ mL
• B. $2.99\times {10}^{-23}$ mL
• C. $2.99\times {10}^{-24}$ mL
• D. $5.99\times {10}^{-23}$ mL

Answer 1

The correct option is A $6.02\times {10}^{-23}$ mL

Therefore one molecule of water$=6.022\times {10}^{-23}$ moles

mass of one molecule of water $=6.022\times {10}^{-23}$ g

Volume of one molecule of water =$\frac{mass}{density}$

=$\frac{6.022\times {10}^{-23}}{1}$ mL

=$6.022\times {10}^{-23}$mL
