Caculate the mass of a solid with a density of 14.2 g/cm cubed and a volume of 350 cm cubed​

Chemistry
1 answer:
shepuryov [24]3 years ago
8 0

Answer:

The mass of solid with density 14.2 g/cm3 and volume 350 cm3 is 4.97 Kg.

Explanation:

Formula for density is given below :

density = \frac{mass}{volume}

volume = 350 cm^{3}

density = 14.2 g/cm^{3}

Insert the values in the formula

14.2 = \frac{mass}{350}

on cross multiplication :

mass = density\times volume

mass = 14.2\times 350

mass = 4970 g

1 g = 0.001 Kg

mass =4970\times 0.001 Kg

mass = 4.97 Kg

Note : Check the units of volume and density carefully

What is the type of weak bond between the hydrogen of one molecule and the nitrogen of another molecule, where the two don't act
Aliun [14]
<h2>Hydrogen Bonding</h2>

Explanation:

  • Hydrogen bonding is a type of weak bond.
  • Hydrogen Bonding occurs when the hydrogen atom of one molecule is bonded with a molecule of high electronegativity element like nitrogen of another molecule.
  • It is a type of dipole-dipole interations.
  • The nitrogen is a highly electronegative element that forms a weak bond with the hydrogen atom of another molecule with dipole-dipole interaction.
  • Hydrogen bonds are weaker than covalent and ionic bonds.
  • Therefore the type of bond is Hydrogen bond.

What is the mass of 8.12 × 10^23 molecules of CO2 gas? (Atomic mass of carbon = 12.011 u; oxygen = 15.999 u.)
amid [387]

Answer:

m=59.3gCO_2

Explanation:

Hello,

In this case, the first step is to compute the molar mass of carbon dioxide as shown below, considering it has one carbon atom and two oxygen atoms:

M=12.011g/mol+2*15.999g/mol\\\\M=44.009g/mol

It is important to notice it is the mass in one mole of such compound. Afterwards, we need to use the Avogadro's number to compute the how many moles are in the given molecules of carbon dioxide as shown below:

mol=8.12x10^{23}molec*\frac{1mol}{6.022x10^{23}molec} =1.35mol

Finally, the mass by using the molar mass:

m=1.35mol*\frac{44.009g}{1mol} \\\\m=59.3gCO_2

Best regards.
