Asked by admin @ in Chemistry viewed by 332 People

The density of a liquid is 1.2 g/mL. There are 35 drops in 2 mL. The number of molecules in one drop

(molar mass of liquid = 70 g/mol) is :1.2NA(4) 1.2NA351.235(3512 NA​

Answered by admin @


Answer:

0.001 NA

Explanation:

2 ml = 35 drops

weight of 2 ml is 2.4 grams( by density )

2ml has 35 drops

so each drop's weight is 0.07g

then,. 70 g = NA molecules

0.07 g = ?

=> 0.001 NA
