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
my
balance the equation: 2naoh + h2so4 = na2so4 + 2h2o
mass of water = 57.8 ml x 1 g/ml = 57.8g
moles of water= 57.8g/ 18.01 g/mol = 3.21
the ratio between h2so4 and h2o is 1: 2
moles of h2so4 required = 3.21/2 = 1.61

Look at the reaction below: ca(hco3)2 --> caco3 + co2 + h2o first, balance the reaction. once balanced, use dimensional analysis or another method to find out how many moles of carbon dioxide will be produced if we start with 16.5 moles of calcium bicarbonate (calcium hydrogen carbonate). = mol of co2 number needs to be reported to three significant figures.
