Given the following equation: N2(g) + 3H2(g) = 2NH3(g).
Determine to one decimal place the molar mass of each term, and WRITE EACH ONE AS A CONVERSION from moles to grams.
I will do one:
NH3=14.0+2*1.0=16.0
1mole=16.0 grams, or Unitconversionfactor= 16grams/mole
N on the periodic table is 14.0067
N2 = 2*14.0067 = 28.0134 which rounds to 28.0 to one decimal place.
1 mole N2 x (28.0 g/mol) = 28.0 grams.
The others are done the same way.
To determine the molar mass of each term in the equation, we will convert the given substances from moles to grams using their respective molar masses. Additionally, we will round the results to one decimal place. Here's the conversion for each term:
1. N2(g)
The molar mass of nitrogen gas (N2) is approximately 28.01 g/mol. Therefore, we can convert moles to grams using the following conversion:
1 mole N2 = 28.01 grams N2
2. 3H2(g)
The molar mass of hydrogen gas (H2) is approximately 2.02 g/mol. Since we have 3 moles of H2 in the equation, we can convert moles to grams using the following conversion:
3 moles H2 = (3 moles H2) x (2.02 grams H2/mole H2) = 6.06 grams H2
3. 2NH3(g)
The molar mass of ammonia (NH3) is approximately 17.03 g/mol. Since we have 2 moles of NH3 in the equation, we can convert moles to grams using the following conversion:
2 moles NH3 = (2 moles NH3) x (17.03 grams NH3/mole NH3) = 34.06 grams NH3
Therefore, rounding to one decimal place, the molar masses of each term in the equation are:
N2(g): 28.0 grams
3H2(g): 6.1 grams
2NH3(g): 34.1 grams
To determine the molar mass of each term in the equation N2(g) + 3H2(g) = 2NH3(g), you need to calculate the molar mass of N2, H2, and NH3. Here's how you can do it step-by-step:
1. Find the molar mass of N2:
- N2 represents a diatomic nitrogen molecule (two nitrogen atoms).
- The atomic mass of nitrogen (N) is 14.01 g/mol.
- Multiply the atomic mass by 2 (since there are two nitrogen atoms in N2) to get the molar mass of N2:
14.01 g/mol * 2 = 28.02 g/mol
2. Find the molar mass of H2:
- H2 represents a diatomic hydrogen molecule (two hydrogen atoms).
- The atomic mass of hydrogen (H) is 1.01 g/mol.
- Multiply the atomic mass by 2 (since there are two hydrogen atoms in H2) to get the molar mass of H2:
1.01 g/mol * 2 = 2.02 g/mol
3. Find the molar mass of NH3:
- NH3 represents ammonia, which consists of one nitrogen atom (N) and three hydrogen atoms (H).
- The molar mass of nitrogen (N) is 14.01 g/mol, and the molar mass of hydrogen (H) is 1.01 g/mol.
- Multiply the molar mass of nitrogen by 1 and the molar mass of hydrogen by 3, then add both values to get the molar mass of NH3:
(14.01 g/mol * 1) + (1.01 g/mol * 3) = 17.04 g/mol
So, the molar masses of each term in the equation are:
- N2(g): 28.02 g/mol (conversion: 1 mol N2 = 28.02 grams N2)
- H2(g): 2.02 g/mol (conversion: 1 mol H2 = 2.02 grams H2)
- NH3(g): 17.04 g/mol (conversion: 1 mol NH3 = 17.04 grams NH3)
Note: The conversions provided indicate that by using the molar mass, you can convert moles to grams and vice versa.
