Answer:
61.09 grams SmO
Step-by-step explanation:
To find the number of grams SmO, you need to multiply the moles by the molar mass of SmO. The molar mass is a ratio which represents the mass of SmO per every 1 mole. It is important to arrange the ratio in a way that allows for the cancellation of units (moles should be in the denominator). The final answer should have 4 sig figs like the given value (0.3672 = 4 sig figs).
Atomic Mass (Sm): 150.36 g/mol
Atomic Mass (O): 15.999 g/mol
Molar Mass (SmO): 150.36 g/mol + 15.999 g/mol
Molar Mass (SmO): 166.359 g/mol
0.3672 moles SmO 166.359 grams
