For the reaction C3H8+5CO2=3CO2+4H2O
How many moles of c3h8 are needed to make 3.6 grams of c3h8? I think the ans is 44.8molesc3h8
3.6 g C3H8 x (1 mole C3H8/44.097 g C3H8) = 3.6 g C3H8/44.097 = ??
sorry correction,
For the reation: C3H8+5 02 =3 CO2+4 H2O
How many moles of C3H8 are needed to make 360 grams of H2O? I think the ans is 44.8molesc3h8
To determine the number of moles of C3H8 needed to produce 3.6 grams of C3H8, you need to use the molar mass of C3H8.
The molar mass of C3H8 is calculated as follows:
(3 x atomic mass of C) + (8 x atomic mass of H)
(3 x 12.01 g/mol) + (8 x 1.01 g/mol) = 36.03 g/mol + 8.08 g/mol = 44.11 g/mol
Now, divide the given mass of C3H8 (3.6 grams) by its molar mass:
3.6 g / 44.11 g/mol = 0.0817 mol
So, you would need approximately 0.0817 moles of C3H8 to produce 3.6 grams of C3H8.
To find the number of moles of C3H8 needed to make 3.6 grams of C3H8, we need to use the molecular weight of C3H8.
The molecular weight of C3H8 can be calculated by multiplying the atomic mass of each atom in the compound and adding them up.
Carbon (C) has an atomic mass of 12.01 g/mol, while hydrogen (H) has an atomic mass of 1.01 g/mol.
(3 * 12.01) + (8 * 1.01) = 44.11 g/mol
Now, we can calculate the number of moles using the given mass and molecular weight:
Number of moles = Mass / Molecular weight
Number of moles = 3.6 g / 44.11 g/mol
Calculating this will give us the answer:
Number of moles = 0.0816 moles
So, the correct answer is approximately 0.0816 moles of C3H8.
