Answer: 6.56g
Explanation:
No of moles = mass given/molar mass
Molar mass of ch4
C is carbon which is 12
H is hydrogen which is 1
Molar mass= 12+4(1)
Molar mass= 16g/moles
No of moles given is 0.41moles
No of moles = mass given/molar mass
Mass given = molar mass × no of moles
Mass given = 16×0.41
Mass= 6.56g
People with a good credit score usually have high salaries and their job is safe, usually in a respectable place or a company. They are known to always pay their debt on time and thus ensure that their credit score is high meaning that there is a chance that they will be given better interests or similar things when they apply for a loan again.
Everything. DNA contains genes and which genes a person has determines which (if any) proteins are formed. Based on how much of a protein is formed determines how strong a trait is expressed. DNA is the genetic material that contains genes. genes contain information about an organisms trait. hope this helps :)
How much of a product is made depends on the limiting reagent. there are different ways to determine the limiting reagent and this depends on the professor way of teaching it. I will use the must common one. so keep in mind that the way to solve this problem may vary.
first we convert each grams to moles using the molar mass of the molecules. then convert moles to moles of asked molecule (H2O) using the mole-mole ration, and moles of water to grams using the molar mass of water.
molar mass of Na= 23.0 g/mol
molar mass of H₂O= 18.0 g/mol
ratios (based on the balanced equation coefficients)
2 mol Na= 1 mol H₂
2 mol H₂O= 1 mol H₂
calculations:
since H₂O gives less of the product than the other one. H₂O is the limiting reagent and the answer is
4.49 g
