Answer:
1.018*10^-2 or 1.018e-2
Step-by-step explanation:
2.245*10-5 lb
So first know that 2.245*10^-5 has 4 sig fig
Then multiply the conversion to cancel lb
1lb = 453.592g
2.245*10^-5 lb * 453.592g/1lb
= 0.0101831404g
Now convert back to scientific notation from general form
0.0101831404g = 1.01831404*10^-2
Then round the number to 4 sf
1.01831404*10-2~ 1.018*10^-2
