The specific gravity of gold is 19.3. What is the length of one side of a 0.4 kilograms cube of solid gold, in units of inches?
zepelin [54]
Specif gravity = density of the material / density of water

density of the material = specific gravity * density of water

density of gold = 19.3 * 1 g/mL = 19.3 g/mL

density = mass / volume ==> Volume = mass / density

Volume = 0.4 kg * 1000 g/kg / 19.3 g/mL = 20.725 mL

Length of one side of the cube = \sqrt[3]{20.725 {cm}^{3} } = 2.75 cm

Pass cm to inches
2.75 cm * 1 inch / 2.54 cm = 1.08 inch

Suppose that NaCl is added to hexane (C6H14) instead of water. Which of the following intermolecular forces will exist in the sy
svet-max [94.6K]

Answer:

Ion-ion force between Na+ and Cl− ions

London dispersion force between two hexane molecules

Explanation:

"Ion-dipole force between Na+ ions and a hexane molecule " does not exist since hexane has only non-polar bonds and therefore no dipole.

"Ion-ion force between Na+ and Cl− ions " exists since both are ions.

"Dipole-dipole force between two hexane molecules " does not exist since hexane molecules do not have a dipole.

"Hydrogen bonding between Na+ ions and a hexane molecule " does not exist since the hydrogen in the hydrogen bond must be bonded directly to an electronegative atom, which hexane does not have since it is a hydrocarbon.

"London dispersion force between two hexane molecules" exist since hexane is a molecular compound.

Proteins have many functions in the cell membrane. Which function is NOT related to a protein?a. transportb. membrane fluidityc.
kirill115 [55]

The function that is NOT related to a protein is:

Membane fluidity.

Membrane fluidity is not related to a protein function because membrane fluidity is a function of lipids not proteins.

Transport and all other options are involved in functions of protein.

D=___g/mL<br> v=100mL<br> m=1.5kg=___g
Bess [88]

The volume is 100mL.

The mass is 1.5kg which is equal to 1500g.

Thus, the density is 1500g / 100mL which is 15g/mL.
