Question

What is the mass of 1.2 moles of C2H6

Answer 1

36 gm

Step-by-step explanation:

From periodic table , mole weight of C2H6 = (2*12) + 6 *1 = ~ 30 gm/mole

1.2 moles * 30 gm/mole = 36 gm

Answer 2

30.07 g in 1 mole C2H6

Step-by-step explanation:

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).
