The mass of 18 ml of water (H2O) at 4° C is equal to Answer: a 18 g Explanation: Desity of water is approximately 1 g cc So 18 ml of water weights 18 gm Weight = volume * density Number of moles = weight molecular weight So here in 18 gm water equal to 1 mole So it contain 6 022*10^23 molecules ie avagadro number of molecules
which would you prefer for measuring the volume of 4. 6 mL, of . . . - Brainly To measure 4 6 ml of milk I will prefer the 50 ml measuring cylinder,for two reasons Reasons: 1)500 ml cylinder is way more large to measure just 4 6 ml of milk 2)500 ml cylinder's lowest mark is 5 ml, which is greater than the milk amount,that we are trying to measure 3)But the 50 ml cylinder has a lowest mark of the 1ml,where we can easily measure our 4 6 ml of milk
