Set up a proportion os V1/n1 = V2/n2. V is the volume, n is the amount in MOLES, not grams. Convert the CO_2 to moles, then solve and find that the amount of N_2 should be the same amount of moles. Then use the molar mass of N_2 (28.02 grams/mole) to convert that amount of moles into grams. That's your answer.
Answer:
Explanation:
Density is found by dividing the mass by the volume.
The mass of the object is 11 grams and the volume is 13 milliliters.
Substitute the values into the formula.
Divide.
Round to the nearest hundredth. The 6 in the thousandth place tells us to round the 4 to a 5.
The density is about <u>0.85 grams per milliliter.</u>
