If the solid after heating has a molar mass of 208 grams per mole and a formula of XY what is the formula of the hydrate?
The molar mass of the hydrated compound is 208 g/mol. To find the formula of the hydrate, we need to determine the molar mass of the anhydrous compound (XY) and subtract it from the total molar mass. With that information, we can calculate the molar mass of water in the hydrate and determine the ratio between XY and water molecules, giving us the formula of the hydrate.
8. On most periodic tables a single atomic mass is listed instead of the mass numbers for all the stable isotopes. How is this mass related to the different isotopes?
In a normal periodic table, the molar mass of a given element, is made up of multiplying the mass of a given isotope of that element, with the abundance of that given isotope in percent. For example, Say for the element X, you know that it has two isotopes, X12 and X13. X12 has a molar mass of 12 g/mol, and you know that of all the X molecules in the world, X12 is found 95% of the time, X13 has a molar mass of 13g/mol, yet its abundence is only 5%. Therefore average molar mass for element X is calculated as such, (12 * .95)+(13*.05) = 12.05 g/mol. hope that helps.

What is the mass in grams of 0.50 moles of BeCI2?
137.4 g First you need to calculate the molar mass of the molecule. Be = 9.01 g/mol C = 12.01 g/mol I = 126.9 g/mol Thus BeCI2 is equivalent to ( 9.01 + 12.01 + 2(126.9) ) g/mol or 274.82 g/mol. Then, using conversions, you multiply the amount you have by the molar mass so that: (.05 mol BeCI2)*(274.82 g/mol). The moles cancel out and you are left with a weight of 137.41 g.
Approximately how many moles are in 300 grams of sulfur?
To determine the number of moles in 300 grams of sulfur, you need to know the molar mass of sulfur. The molar mass of sulfur is 32.06 g/mol. You can calculate the number of moles by dividing the given mass by the molar mass: 300 g / 32.06 g/mol ≈ 9.35 moles.

How do you clean Mass air flow sensor on a 1998 Nissan Altima?
how do you clean mass air flow sensor on a 1998 Nissan altima? To clean the mass air flow sensor , you need to get a can of CRC mass air flow cleaener frm auto zone, Kragen, Pepboys, Sensor is attached to the tube (next to airfilter). again you need to use mass air flow cleaner ( CRC ). I use this on my ford windstar and Nissan sentra 05 and 95. it runs better after cleaning the mass air flow sensor.
