Answer:
584.2 g
Explanation:
Hello there!
In this case, since we know the 20% of the atoms correspond to sodium, we can compute the total atoms as shown below:
Which are also equal to 1 mol and the Avogadro's number of sodium chloride with a molar mass of 58.44 g/mol; thus, the grams of salt turn out to be:
Best regards!
Density = mass/ volume
mass= 9.6 g
Volume of the object = 13.2-10.0 =3.2 ml=3.2 cm³
1ml =1 cm³
D=9.6g/3.2 cm³ = 3.0 g/cm³
The role of the salt bridge is to assure the neutrality of both compartments.
