There are 1.456 moles of hydrogen in 5.2 moles of C7H18
Answer:
Heterogenous
Explanation:
Mud is a mixture of water and soil
It is to be assumed that the unit of the given concentration is in molarity. To determine the number of moles given molarity and volume, we use the equation,
m = (M)(V)
volume should be in liters. Substituting the known values,
m = (0.350)(0.40 L)
m = 0.14 mols
Then, multiply the number of moles by the molar mass of KOH which is equal to 56.1056 g/mol.
mass = (0.14 mols)(56.1056 g/mol)
mass = 7.855 grams
Answer: 7.855 grams
Answer: Fe2O3
Explanation: By applying crisscross method, the formula will be Fe2O3.
That is called condensation
