according to the balanced equation 1 mole of H2SO4 produces 2 moles of water (18 \(\times\)2=36grams). ok ?

OpenStudy (abhisar):

Now density of water is given 0.987 g/mL, so 1 mL of water = 0.987 gram. Thus, 57.8 mL = 0.987\(\times\)57.8=57.086 gram

OpenStudy (superhelp101):

alright

OpenStudy (abhisar):

Now since 1 mole of H2SO4 produces 36 gram of water how many moles will produce 57.086 gram water ?

Find it, that will be the answer
