Determine the mass of 5.20 moles of C6H12

Chemistry

Vera_Pavlovna [14]3 years ago

Hello!
We have the following data:

m (mass) = ? 
n (number of moles) = 5.20 moles
MM (Molar mass of C6H12) 
C = 6*12 = 72 amu
H = 12*1 = 12 amu
--------------------------
MM (Molar mass of C6H12) = 72 + 12 = 84 g/mol

Now, let's find the mass, knowing that:

n =  \dfrac{m}{MM}

5.20\:\:\diagup\!\!\!\!\!\!\!mol =  \dfrac{m}{84\:g/\diagup\!\!\!\!\!\!\!mol}

m = 5.20*84

\boxed{\boxed{m = 436.8\:g}}\end{array}}\qquad\checkmark

Complete the isotope symbol with mass numbers of 35
amid [387]
The answer would be
35 ============= > A CL = ============> CL 17 === = ======== >Z 
37 CL 17 Isotopes mean A different and equal Z.
Isotopes are atoms that have the same number of protons but a different number of neutrons but still belong to the same element. Though they have the same atomic number but not the same mass number.

Answer:

Answer B

Explanation:

By definition mixtures are combinations of substances physically prepared and physically separated. Mixtures are classified as 'homogeneous mixtures' and 'heterogeneous mixtures'. For homogeneous mixtures all components are dissolved, with solute evenly distributed throughout the solution and assumes state of solvent. 'Heterogeneous mixtures' have inconsistent properties throughout and solute concentration is not consistent throughout the mixture.

Calculate the number of different atoms in 0.2 mol ethene​
muminat

Answer:

1.204 × 10²³

Explanation:

The number of atoms in a mole is always 6.022 × 10²³, known as Avogadro's number or Avogadro's constant.

To convert moles to atoms, multiply the molar amount by Avogadro's number.

(6.022 × 10²³) × 0.2

         = 1.204 × 10²³

How to balance and classify these equations?1-13
andrew-mc [135]
Well first you need to convert all the substances into there other name. For example: you would change #1 to Mg+O=MgO. That would be known as a synthesis reaction.
