## anonymous one year ago If 0.274 moles of a substance weighs 62.5 g, what is the molar mass of the substance?

1. Rushwr

There is a standard equation for this. $no. of moles = \frac{ mass }{ molar mass }$ They have given us the mass and the no. of moles right? Just subject molar mass in the above equation. $molar mass = \frac{ mass }{ moles }$
