tensa zangetsu [6.8K]

0.761 mol of C_7H_{16}  would you have if you have 76.36 grams.

<h3>What is a mole?</h3>

A mole is defined as 6.02214076 × 10^{23}of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

Given data:

Mass=76.36 grams

Moles = \frac{mass}{molar \;mass}

Moles = \frac{76.36 grams}{100.21 g/mol}

Moles = 0.761

Hence,  0.761 mol of  C_7H_{16} would you have if you have 76.36 grams.
