What mass of AuClz (MW 303 g/mol) contains 5.0 x 1023 atoms of Cl? O 120 g O 28 g 0.83 g 0 84 g 0 760 g​

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.
