A reaction produces 0.837 moles of H 2 O . How many molecules of H 2 O are produced?
AleksAgata [21]

Answer:

5.04 * 10^2^3

Explanation:

The original calculation to find the number of moles which is n=\frac{m}{M} can be rearranged to give the equation m=nM. Therefore the amount of molecules can be found by m = 0.837 *6.02*10^2^3 (multiplying by Avogadro's Number)

Hydrogen reacts with 0.771 g of carbon to form 0.90 g of a compound. What is the mass percent of hydrogen in the compound
morpeh [17]
Answer: 14.3%

Explanation: In order to find the mass percent of hydrogen in this compound, you must determine how many grams of hydrogen you'd get in 100 g of compound. 

In your case, you know that an unknown mass of hydrogen reacts with 0.771 g of carbon to form 0.90 g of hydrocarbon, which is a compound that contains only carbon and hydrogen. 

Use the total mass of the hydrocarbon to determine how many grams of hydrogen reacted with the carbon.

Now, if 0.90 g of this compound contain 0.129 g of hydrogen, it follows that 100 g of this compound will contain.

So, if 100 g of this compound contain 14.33 g of hydrogen, it follows that the mass percent of hydrogen is 14.3%
