Question

Determine the mass of 10.2 mol ethane (C2H6) mass = ___ g

Answer 1

Answer:

We also know that 1 mole of C atoms weighs 12.01 g and 1 mol of H atoms weighs 1.0079 g. So, we know the molar mass of ethane also. Or, 30.07 g in 1 mole C2H6. So, we say the molar mass of ethane is 30.07 g/mol (that's grams per mole).

PLS make my answer brilliant PLS

Answer 2

Determine the mass of 10.2 mol ethane (C2H6) mass = ___ g

30.07 g/mol

A mole is defined as the amount of substance contains the same number of discrete atoms, molecules, and ion as the number of atoms in a sample of pure 12C weighing exactly 12 g.

The molar mass of an element (or compound) is the mass in grams of 1 mole of that substance and it is expressed in units of grams per mole (g/mol)
