1.74 liters of gas at STP are pumped into a basketball, how many moles of gas are in the basketball? Assume the basketball was completely empty prior to filling it with gas.

Which fact represents evidence for the big bang theory?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

Draw a line graph showing the relationship between temperature in kelvin as a function of kinetic energy.
