Round correctly for full credit. Direct link to Richard's post If the number of moles of, Posted 2 years ago. Polymers are large molecules composed of simple units repeated many times. How many grams C2H6 in 1 mol? A. 12 kcal A. 'cause I am rounding. A. B. A. specific heat However, this problem asks us to solve for the number of moles of gas, or n. To do this, you can solve for n in the equation as Sal did, and get n = PV / RT. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. Since Avogadro's number is a measured quantity with three significant figures, the result of the calculation is rounded to three significant figures. Sal is using the ideal gas law which assumes the gases to be ideal. Convert between C2H6 weight and moles. And then, I'm gonna multiply B. ten grams of water occupies a larger volume than 10.0 g of aluminum B. The first conversion factor converts from moles of particles to the number of particles.

The answer is 30.06904. D. 6.67 M, What is the molarity of a solution that contains 17 g of NH3 in 0.50 L of solution? mol ethane This problem has been solved! If we know the formula of a compound, determining the molar mass is simple. Finding molar mass starts with units of grams per mole (g/mol). EE means times 10 to the, times 10 to the 23rd, is equal to that. Type in unit Upvote 0 Downvote. D. 1700 cal. Advertisement BarrettArcher C. 6.74 g D. 33 mL, How many moles of are in 250 mL of a 3.0 M of CaCl2 solution? Please enable Javascript to use The formula C2H6 shows that there are two carbon atoms in each molecule of . D. shows a gain of electrons. B. B. But they do tell us that each millimeter of mercury is equal to a Torr. 1 x 10-5 Direct link to anomaly.performance's post At 5:08 Sal divided by th, Posted 2 years ago. B.
