Answer:
170.38g is the mass of 1 mole of C₁₂H₂₆
Explanation:
To solve this question we must find the molar mass of the alkane C₁₂H₂₆. The molar mass is defined as the mass of one mole of a substance.
In 1 mole of C₁₂H₂₆ we have 12 moles of Carbon and 26 moles of Hydrogen. With the periodic table of elements we can know the molar mass of 1 mole of Carbon and 1 mole of hydrogen, and, thus, the molar mass of the alkane (Molar mass C = 12.01g/mol, H = 1.01g/mol)
<em>Molar mass C₁₂H₂₆:</em>
12C = 12*12.01g/mol = 144.12g/mol
26H = 26*1.01g/mol = 26.26g/mol
144.12g/mol + 26.26g/mol =
<h3>170.38g is the mass of 1 mole of C₁₂H₂₆</h3>
Answer:
Explanation:
an atom consists of prontons electrons and neutrons.
The nucleus is positively charged proven by the Rutherford experiment. The protons and neutrons are in the nucleus so the charges cancel out. The electrons are surrounded in the shells that are negatively charged.
