The conversion factor between mass and moles for a compound is the molar mass. true false

true

Explanation:

Moles -

Moles is denoted by given mass divided by the molar mass ,

Hence ,

n = w / m

n = moles ,

w = given mass ,

m = molar mass .

From the above equation , if two of the quantity is known then the third quantity can easily be determined , by using the above formula ,

i.e. ,

n = w / m

In case , mole ( n ) and mass ( w ) , is known , the value of the molar mass can be determined easily .

Hence ,

The given statement of the question is true.
