Question

Calculate the mass in grams of a 1.070 mole of acetylene ,C2H2

Answer 1

n=1.070 mole
Molar mass= 26.04 g/mol
mass=?
m=nM = (1.070 mole)(26.04g/mol) =27.8628 g

Answer 2

27.86x10^-3 Kg

Step-by-step explanation:

Hi! To get the result you only need to use this formula: m = n x M <=> m = 1.070 x ((2x12.01 + 2x1.01) x 10^-3) = 27.8628 x 10^-3 Kg. Hope it helped!
