Answer 1

Answer:

1.8 ml will have = 6.022×10^23×1.8×10/22.4 ×1000=6.022×10^21×1.8/22.4.

Answer 2

for water 1cm³ = 1mL

so, it can be written as 1.8 cm³ of water

and the density of water is 1gm/cm³

so it can be further simplified and written as 1.8 gm of water

moles of water = 1.8/18, here 18 is the molar mass of water.

moles = 0.1

number of molecules = moles × avogadro number

no. of molecules = 0.1×6×10²³ = 6×10²²
