Question

How many moles of ch4 are contained in 112 g of that substance? the molar mass of ch4 is 16 g/mol.

Answer 1

To find the number of moles of CH4 in 112 grams, divide the mass by the molar mass of CH4, which is 16 g/mol, yielding 7 moles of CH4.

Step-by-step explanation:

To determine how many moles of CH4 are contained in 112 grams of that substance, you would use the formula:

moles of CH4 = mass of CH4 (in g) / molar mass of CH4 (in g/mol)

Given the molar mass of CH4 is 16 g/mol, we calculate as follows:

moles of CH4 = 112 g / 16 g/mol = 7 moles

Therefore, 112 g of CH4 contains 7 moles of the substance.
