Three of them
3 sig figs.
1 gram = 1000 mg 1 kg = 1000 gram = 2.2 pounds 2500 mg = (2500/ 1000/1000) x 2.2 kgs
150 grains equates to about 9719.84mg
0.05 mg medicine is twice as strong as 0.025 mg.

2.0 lbs x 453.6 g/lb x 1000 mg/g = 907,200 mg rounded to 9.1x10^5 mg = 910000 mg (2 sig figs based on the value 2.0)
1 mole of MgCl2=95.21 grams (found on the periodic table) 17.5 g of MgCl2(1mole of MgCl2/95.21g of MgCl2)=.184 moles of MgCl2(grams cancel out and rounded to 3 sig. figs) .184 moles of MgCl2 (1 Liter/2.5 moles of MgCl2)=0.735L of MgCl2 (moles cancel and rounded to 3 sig figs) 0.735 L of MgCl2(1000 milliLiters/1 Liter)=73.5 mL of MgCl2 and round the answer to 2 sig figs which equals 74 milliLitersof MgCl2
Trailing zeros after a decimal point are not normally written. As trailing zero s have been written they must be significant; thus 0.050200 mg has 5 sig fig.
The doctor is prescribing Augmentin ES 600 mg tablets. Sig is code for Instructions. BID means twice daily. So the doctor is saying dispense #24 Augmentin tablets and the patient needs to take 2 tablets twice daily.

1 mg ÷ 0.125 mg = 8
To determine how many 0.5 mg units are in 0.25 mg, you divide 0.25 mg by 0.5 mg. Thus, 0.25 mg ÷ 0.5 mg = 0.5. Therefore, there are 0.5 units of 0.5 mg in 0.25 mg.
