what mass of oxygen is required to react with 160 g of sulfur? Is my work right?

Question

S(s)                                                          + O2(g) ---- SO2(aq)

m=160                                                         m=??

M=32.07                                                      M=32.00

160 divided by 32.07=4.989086374                

so 5.00 moles

                                      5.00*1:1=5.00                         5.00*32=159.650764 or according to sig digs it would be 160g 

Answer 1

Yes, your steps look great. Be careful with your rounding though. Why did you round the moles of S to 5.00? And your final answer to only two sig figs?
