1. The problem statement, all variables and given/known data At 1000 deg C and 10 torr, the densit of a certain element in the gaseous state is 2.55×10^-3 g/L. The element is: 2. Relevant equations 3. The attempt at a solution So, i took the the density equation, that of which is derived from the ideal gas law, and rearranged to solve for the molar mass, but, unfortunately, it did not suceed. What am I to do to solve this problem?
