3.15 mol of NO2 gas at STP will occupy how much volume?

One of the decomposition products of ammonium nitrate can be dinitrogen monoxide.  How many milliliters of dinitrogen monoxide gas at STP are made from the decompostion on 0.87 grams of ammonium nitrate in significant figures?

Select all the statements that apply to Charles's law. Charles's law relates gas volume and temperature in Kelvin. The volume of as is proportional to its temperature in degrees Celsius or Kelvin. The volume of a gas decreases as temperature increases if the gas is kept at a constant pressure and fixed amount. ✔The volume of a gas increases as temperature increases if the gas is kept at constant pressure and fixed amount.
