Question

How many moles of sulfuric acid are needed to produce 57.8 milliliters of water? Water has the density of 0.987 g/mL. Show all steps of your calculation as well as the final answer.

NaOH + H2SO4 → Na2SO4 + H2O

Answer 1

@Abhisar

Answer 2

do i have to balance the equation first?

Answer 3

1 mL of water = 0.987 gram of water

Answer 4

yes balancing is must

Answer 5

now calculate the amount of water in grams for 57.8 milliliters

Answer 6

balancedd equation: H2SO4 + 2 NaOH -> Na2SO4 + 2 H2O
grams: 57.0486

Answer 7

ok

Answer 8

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

Answer 9

how do i solve that?

Answer 10

solve what ?

Answer 11

i mean what do i do after i found in grams and the balaced equation

Answer 12

i am explaining u that only. Respond to my questions. U got the above line ?

Answer 13

yea

Answer 14

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

Answer 15

alright

Answer 16

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

Answer 17

Find it, that will be the answer

Answer 18

1.58?
