What is the mass of 2 moles of C2H2?

-------------------------------------------------------

answers:
say: 1 mole of C2H2 has a molar mass of 26 g (google will give you that).

2 moles, 2 * 26 g.

electron1 say: The mass of one mole of carbon is 12 grams. The mass of one mole of hydrogen is 1 gram.
For C2H2, mass of one mole = 12 * 2 + 1 * 2 = 26 grams
The answer is 52 grams.

Ash say: Molar mass of a substance gives mass of 1 mole of a substance
So 2 moles will give 2 times molar mass

Molar mass of C2H2 = 26.04 g/mol
which means 1 mol of C2H2 is 26.04 g
then 2 mol of C2H2 will be 2x26.04 = 52.08 g
