15.6 kg is equivalent to 15600 g The molar mass of acetone is 58 g/mole Therefore; 15600/58 = 269 moles 1 mole of acetone contains 3 × 6.022 × 10^23 atoms Therefore, 269 moles of acetone would contain; 269 × 3× 6.022 ×10^23 atoms = 4.86 ×10^26 atoms of carbon
Answer is: 4,859·10²⁶ atoms of carbon. m(CH₃COCH₃) = 15,6 kg · 1000 g/kg = 15600 g. n(CH₃COCH₃) = m(CH₃COCH₃) ÷ M(CH₃COCH₃). n(CH₃COCH₃) = 15600 g ÷ 58 g/mol. n(CH₃COCH₃) = 268,965 mol. N(CH₃COCH₃) = n(CH₃COCH₃) · Na. N(CH₃COCH₃) = 268,965 mol · 6,022·10²³ 1/mol. N(CH₃COCH₃) = 1,619·10²⁶. There is three atoms of carbon in one molecule of acetone, so: n(C) = 3 · 1,619·10²⁶ = 4,859·10²⁶.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )
