The density of a liquid can be determined by weighing a known volume of the liquid in a graduated cylinder. the data from the ex

Kipish [7]

Answer:- density of the liquid is 0.21 gram per mL.

Solution:- $density=\frac{mass}{volume}$

From given data, mass of cylinder = 10.4 g

mass of cylinder along with liquid = 11.7 g

So, mass of liquid = 11.7 g - 10.4 g = 1.3 g

Volume of liquid = 6.2 mL

Let's divide the mass by the volume to get the density of the liquid:

$density=\frac{1.3g}{6.2mL}$

density = $0.21\frac{g}{mL}$

So, the density of the liquid is 0.21 gram per mL.

what is the suggested weight of the sample that should be disssolved in the beaker before it is transferred to the NMR tube

sukhopar [10]

The sample must be sufficiently soluble (fig. 2) to yield an NMR spectrum. For 1H and 1H observed NMR, it is recommended to dissolve between 2 and 10 mg in between 0.6 and 1 mL of solvent so that the sample depth is at least 4.5 cm in the tube (fig. 3).
