What is the mass of 2 mol of C25H52?

1 answer

To calculate the mass of 2 mol of C25H52, we first need to calculate the molar mass of one molecule of C25H52.

The molar mass of carbon (C) is approximately 12.01 g/mol
The molar mass of hydrogen (H) is approximately 1.008 g/mol

Molar mass of C25H52:
(25 x 12.01 g/mol) + (52 x 1.008 g/mol)
= 300.25 g/mol + 52.416 g/mol
= 352.666 g/mol

Now, we can calculate the mass of 2 mol of C25H52:
2 mol x 352.666 g/mol = 705.332 g

Therefore, the mass of 2 mol of C25H52 is 705.332 grams.
