<em>Most accurate. A pipette prived the most accurate method for delivering a known volume of solution, for example, a 10mL transfer pipette has an accuracy of ±0.02mL</em>
A graduated cylinder is specifically used to deliver a known volume, its typical accuracy is ±1%, this means that a 100ml graduated cylinder is accurate to ±1mL.
A beaker is a multipurpose cylindrical glass mainly used to hold liquids. Even though they are graduated, these marks are an estimation, the beaker's accuracy is around 10%.
Least accurate. A balance measures an object's mass, even though water's density is close to 1, a balance is not the ideal equipment to measure volume, its capacity usually goes between 100-200grams and can measure mass to the nearest ±0.01mg to ±1mg.
I hope you find this information useful and interesting! Good luck!
From the Graham's law of effusion; R1/R2 = √MM2/√MM1 Molar mass of chlorine gas is 71 Therefore; 1.87= √ 71 /√mm1 = 1.87² = 71/mm1 mm1 = 71/1.87² = 71/3.4969 = 20.3 Thus, the molar mass of the other gas is 20.3 , and i think the gas is neon
