The number 250 mg tablets of Metronidazole that are needed to make 150 ml of suspension containing 100 mg/ml
250mg= 150 ml
what about 100 ml = ? Mg
by cross multiplication
150 ml x 250 mg/100 ml = 60 Mg of 250 mg is needed
2 H2 + O2 ----------- 2 H2O
2 mol H2 ----------- 1 mol O2
27.4 mol H2- ------ x mol O2
2x = 27.4
x = 27.4 / 2
x = 13.7 moles O2
answer b
hope this helps!.
