Given the reaction: 2C2H2(g) + 502(g) → 4CO2(g) + 2H2O(g)
What is the total number of grams of O2(g) needed to react
completely with 0.50 mole of C2H2(g)?

A)40 g
B)160 g
C)10 g
D)80 g

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
