micro-syringe has a maximum volume of 50 mL. A chemical reaction known to generate methane gas is sampled using the syringe twice. The first sample with a volume of 10.0 mL was determined to contain 5.98 x 10-7 moles of methane gas. If a second sample of 25.0 mL was taken, with the reaction at the same temperature and pressure, how many moles of gas are in the 25.0 mL sample?
