Question

What is the total mass in grams of 0. 75 mole of so2.

Answer 1

Answer:

48.075g(or 48g in correct sig figs)***

Explanation:

$\frac{0.75mol}{1} *\frac{64.1g}{1 mol}$=48.075g

*64.1g is the mass of SO2 which is calculated by simply taking the mass of sulfur and oxygen(but doubling it since there are two oxygens) and adding them together(32.1+2x16.0)

**btw the mol units cancel because of dimensional analysis in case anyone was wondering why

***if your teacher is like mine and specifically wants your answer in correct sig figs, use the answer in parentheses as the original problem only has 2 sig figs
