You have two beakers, one filled to the 100 ml mark with sugar (mass of sugar 180.0 g) and the other filled to the 100 ml mark with water (the water has a mass of 100.0 g). you pour all the sugar and all the water together in a bigger beaker and stir until the sugar is completely dissolved. a. which of the following is true about the mass of the solution. explain. i. it is much greater than 280.0 g. ii. it is somewhat greater than 280.0 giii. it is exactly 280.0 giv. it is somewhat less than 280.0 gv. it is much less than 280.0 gb. which is true about the volume of the solution. explain. i. it is much greater than 200.0 mlii. it is somewhat greater than 200.0 mliii. it is exactly 200.0 mliv. it is somewhat less than 200.0 mlv. it is much less than 200.0 ml

Ok so co(g) is not pronoused that. the only clue is that youpronouse it the oppisote way. 

Use the universal gas law formula: pv = nrt now, the key word in this problem is stp, so at stp, temperature will always be 0 degrees celsius and pressure will always be 1.0 atm or 760 torr. given something is at stp, we already know the two variables pressure and temperature. the other thing we can find with the given information is moles. to find moles, just divide grams by molar mass of the element. 16.0g / 2(16.00)g/mol = 0.5 moles plug the values in to the equation pv = nrt (1.0 atm)( x ) = (0.5 )(0+273=273k) the r value is just a constant for when we use atm, liters, moles and kelvin. i'm assuming you want your answer in liters, but if you dont just move the decimal 3 to the right in your final answer. so when plugging these numbers in to your calculator and trying to find x, you get 11.20665 liters using significant figures the answer is 11.2 liters
